Tips for every method
These work for every decoration method. Then jump to your method for the specifics.
Using a specific tool?
--no (for example --no text, gradient, shadow), and set a shape with --ar (for example --ar 3:1 for a wide banner).Screen printing
What works best: Bold designs in a few solid spot colors. Great for larger runs.
Screen printing uses one screen for each ink color, so flat, solid “spot” colors work best. We print up to 6 spot colors, plus a white underbase on dark garments. Fewer colors (1 to 4 is common) means less setup. We’ll confirm on your proof.
Smooth gradients and photo shading can’t print as they are. Shading is done with a dot pattern called a halftone, or with solid highlights and contrasting shapes.
✔ Do
- Use up to 6 solid spot colors (fewer is better), plus a white underbase on dark garments.
- Keep lines at least 1 pt (about 0.35 mm) thick and gaps or open spaces at least 2 pt (about 0.7 mm) wide at print size.
- Use bold, flat shapes with strong contrast against the garment color.
- Ask for a flat, vector-style design on a transparent or white background.
✘ Don’t
- Use gradients, glows, transparency or photo shading. Use halftone dots or solid highlights instead.
- Use tiny lettering, thin fonts, hairlines or small dots.
- Use more colors than the design really needs.
Full checklist: 20 screen printing tips
- Vector art is best: clean, scalable shapes, smooth curves and clear edges (SVG, AI, EPS or vector PDF). Most AI tools make pixel images, and that’s OK: we can vectorize them.
- Design for spot colors: a limited number of solid ink colors, not full-color photo effects.
- Use as few ink colors as the design needs. 1 to 4 is common; our maximum is 6 spot colors plus a white underbase. Every screen adds setup.
- Use solid, opaque colors. No transparency, blend modes or semi-transparent shapes, unless they’re turned into halftones on purpose.
- Skip unnecessary gradients. Shade with halftone dots, solid highlights or contrasting shapes.
- Keep lines at least 1 pt (about 0.35 mm) thick and gaps or open spaces at least 2 pt (about 0.7 mm) wide at the final print size.
- Keep text easy to print: no very small lettering, very thin fonts or intricate script details.
- Use negative space, and let the garment color be part of the design.
- Dark garments usually need a white underbase under the colors. It counts as an extra screen.
- Avoid fine details like tiny dots, hairlines and narrow enclosed spaces.
- Colors are slightly overlapped (trapped) so small shifts on press don’t leave gaps or show the underbase. We handle this.
- Avoid huge areas of solid ink. They make the print heavy and stiff.
- Keep each color clearly separate so the design splits cleanly into screens. We handle the separations.
- Have brand colors? Send your Pantone (PMS) numbers and we’ll match them as closely as we can.
- Design at the final print size.
- Avoid thin details that have to line up perfectly between two colors.
- Use halftones only when they can be reproduced. About 40 to 55 lines per inch is typical, depending on the screen. We’ll confirm on your proof.
- Make sure the design contrasts strongly with the garment color.
- Keep the file clean: no overlapping shapes, hidden objects, stray paths or duplicates.
- Simpler is more efficient: fewer colors, simpler separations and easier lineup on press.

Please create artwork for screen printing on a shirt. Make it a flat, vector-style design with clean, bold shapes, smooth curves and clearly defined edges. Use only solid spot colors: no more than 6, and fewer is better, since 1 to 4 colors is often enough. Do not use gradients, photo effects, shadows, glows, transparency or 3D effects. If the design needs shading, use simple solid highlights or a halftone dot pattern. Keep every line at least 1 pt thick and every gap or open space at least 2 pt wide at the final print size, and avoid hairlines, tiny dots and very small or thin lettering. Let the shirt color show through as part of the design, and make sure the colors contrast strongly with the shirt. Put the design on a plain white or transparent background, centered, with no mockup, and leave out any words unless I ask for them. Make it as large and sharp as possible. My design:
For example, after “My design:” type: a howling wolf head in navy and gold for the front of a gray t-shirt, about 11 inches wide.
Embroidery
What works best: Bold, simple shapes in a few solid thread colors.
Embroidery is sewn with thread, so design for stitches, not pixels. Before we can stitch your design, it’s digitized: turned into a stitch file that tells the machine where every stitch goes.
Thread can’t show gradients, hairlines or tiny lettering. And think small: a left-chest logo is usually about 3.5 to 4 inches wide.
Good to know: An AI-made image or SVG isn’t a digitized embroidery file. It still has to be digitized into stitch data and tested before it’s stitched.
✔ Do
- Use bold, simplified shapes with thick outlines.
- Keep to 1 to 6 thread colors, with clear contrast.
- Make lettering at least about 1/4 inch (6 to 7 mm) tall, in a bold font. We’ll confirm on your proof.
- Picture the design at its real size and location before you send it.
✘ Don’t
- Use gradients, soft shading, glows or photo detail.
- Use thin lines (keep decorative lines about 1 mm or thicker), tiny isolated details or thin borders.
- Fit lots of small words into the design.
Full checklist: 20 embroidery tips
- Design with stitches in mind, not pixels.
- Use bold, simplified shapes.
- No gradients or photo effects. Use solid thread colors or simple shading.
- Keep to 1 to 6 thread colors.
- Make lettering about 6 to 7 mm (about 1/4 inch) tall or larger. We’ll confirm on your proof.
- Use bold, clean fonts, not thin ones.
- Make decorative lines about 1 mm thick or more.
- Different parts use different stitches: satin for narrow borders and lettering, fill for large areas, running stitch for simple details. We handle this when we digitize.
- Avoid tiny isolated elements.
- Leave enough space between elements.
- Avoid unnecessary large or overlapping filled areas. They add stitches.
- Connected shapes and grouped colors stitch more cleanly, with fewer thread trims and jumps.
- Fabric can pull and stretch while it’s stitched, so simple shapes hold up best.
- Very wide satin areas are stitched as fill instead. We handle this.
- Design for the location: a left-chest logo (about 3.5 to 4 inches wide) needs far less detail than a jacket back.
- Fabric matters: fleece, performance polos, caps and structured jackets all stitch differently. Tell us what you’re ordering.
- Simplify complex logos while keeping what makes them recognizable.
- Use borders sparingly, and avoid thin borders or borders close to other elements.
- Choose thread colors that contrast clearly.
- Stitch density, underlay and stitch order are set when we digitize your design.

Please create a logo for embroidery. Design it for stitches, not pixels: bold, simple, flat shapes with thick outlines and solid colors. Use 1 to 6 thread colors, and pick colors that contrast clearly with each other and with the garment. Do not use gradients, photo effects, soft shading, glows or 3D effects. Avoid thin lines, tiny isolated details, small dots and thin or close-set borders; any decorative line should be about 1 mm thick or more at the real size. Leave space between shapes so they don't run together. If there is lettering, make it bold and simple, at least about 1/4 inch (6 to 7 mm) tall at the real size, with no thin or script fonts. It may be small, like a left-chest logo about 3.5 to 4 inches wide, so keep it simple enough to read at that size. Use a plain white background, centered, with no mockup. My design:
For example, after “My design:” type: a coffee cup with rising steam in dark brown, tan and cream, for a left-chest logo about 3.5 inches wide.
DTF & Full-Color Digital Prints
What works best: Full color is fine. You need a sharp 360 DPI file with crisp, solid edges.
DTF (direct-to-film) and other digital transfers print your design in full color onto a film that’s heat-pressed onto the garment. Full color, gradients and realistic shading inside solid areas are all fine, and it works well for small runs.
What matters most is a sharp, high-resolution file with a clean, truly transparent background.
✔ Do
- Go full color. Gradients, shading and photo-real art are all OK inside solid areas.
- Ask for 360 DPI art at the full print size. For a design printed 10 inches wide, that’s about 3,600 pixels wide.
- Keep lines and the gaps between them at least 2 pt thick (about 0.7 mm, roughly 1/32 inch) at the actual print size, including thin outlines, small text and fine details.
- Use a truly transparent background with crisp, solid edges, and ask the AI for the biggest version it can make.
✘ Don’t
- Use fades or gradients that fade out to transparent, soft glows or semi-transparent areas. Gradients inside solid areas are fine, but fades to transparent don’t print cleanly on DTF.
- Leave a faint white “haze,” feathered edge or stray pixels around the art. They can print as a visible outline or box.
- Use hairline strokes or very thin lines/gaps. Lines thinner than 2 pt may not transfer or can peel.
- Leave tiny floating specks or splatter, or stretch a small, blurry image to make it bigger.
Full checklist: 20 DTF & full-color digital print tips
- Design for full-color digital printing.
- Make your art 360 DPI at the final print size (10 inches wide is about 3,600 pixels). Vector art can be scaled to any size.
- Use a truly transparent background: no white rectangle and no garment-colored background.
- Keep edges clean: no stray pixels, blocky JPEG artifacts, feathered outlines or semi-transparent halos.
- Keep lines and the gaps between them at least 2 pt (about 0.7 mm, roughly 1/32 inch) at the final print size.
- Make small lettering readable: bold fonts with enough space between letters.
- Gradients and realistic shading inside solid areas are OK.
- Avoid fragile isolated details like tiny dots and disconnected bits.
- Avoid huge solid blocks of color. They make a heavy transfer.
- Use negative space so the garment shows through.
- Make sure the design contrasts with the garment color, especially on dark fabric.
- Make white areas truly white and transparent areas truly transparent. We create the white ink layer for you.
- No glow effects or faint transparent fades.
- Use solid edges, with no fades to transparent.
- Start in full color (RGB or sRGB).
- DTF doesn’t print metallic, neon or reflective inks. Those looks can only be imitated with regular colors.
- Don’t add extra borders or backgrounds around the graphic.
- Keep the detail realistic for the actual print size.
- Gang sheets (several designs on one sheet) are arranged and spaced by our team.
- The ideal file is a transparent 360 DPI PNG at the finished size, or a true vector file.

Please create a full-color design for a DTF (direct-to-film) shirt transfer. Full color, gradients and realistic shading are fine inside solid areas. Put the design on a truly transparent background, with no white box, no background color and no border around it. Give it crisp, solid edges: no fades to transparent, no soft glows, no semi-transparent areas, no feathered outlines and no white halo or haze around the edges. Keep every line, and every gap between lines, at least 2 pt (about 0.7 mm) thick at the final print size, including thin outlines, small text and fine details. Avoid tiny floating specks, splatter and loose, disconnected bits. Make the colors stand out against the shirt color. Don't rely on metallic, neon or reflective effects, and don't show a mockup. Make the image as large and sharp as possible, ideally enough for 360 DPI at the final print size. My design:
For example, after “My design:” type: a sunset over a lake with a small fishing boat in a retro poster style, about 11 inches wide on the back of a black shirt.
Laser engraving
What works best: High-contrast black-and-white line art with clean, closed shapes.
A laser marks one “color”: the area it engraves. So the best art is black-and-white, high-contrast line art, ideally clean vector shapes. Color and gray shading don’t carry over. If you want texture, ask for an “engraving style” or “woodcut style” made of lines and dots.
We laser engrave drinkware and tumblers, wood, leather and acrylic, and each material engraves a little differently. We’ll confirm on your proof.
✔ Do
- Ask for black-and-white line art with high contrast.
- Use clean, smooth, closed shapes and solid lines.
- Ask for “engraving style” if you want texture or shading.
- Build it for the real item and size, and keep it simple enough for the material.
✘ Don’t
- Use color, gray tones, gradients or simulated shadows.
- Use very thin features or tiny details.
- Use big solid filled areas, or send a photo and expect it to engrave like a photo.
Full checklist: 20 laser engraving tips
- Vector art (clean SVG paths) works best.
- Keep it mostly black and white.
- Use high contrast so it’s clear what gets engraved and what doesn’t.
- Avoid gray tones, unless you’ve asked for photo engraving on a material that suits it.
- Match the detail level to the material and the size.
- Avoid very thin features.
- Avoid unnecessary large filled areas.
- Thin outline work engraves cleanest as clean vector lines.
- If a piece needs cutting as well as engraving, we set up the engrave and cut parts separately.
- Use closed shapes for anything that’s filled or cut.
- Avoid duplicate or overlapping paths.
- Build the design at its real size.
- Each material engraves differently: wood, leatherette, glass, acrylic, anodized aluminum and powder-coated metal.
- Engraving can darken the material or reveal a lighter layer underneath, so design for how it will look.
- Simplify intricate designs for textured or uneven surfaces.
- Some items need their own version, like a reversed design for a powder-coated tumbler versus wood or glass. We’ll confirm on your proof.
- Leave a margin around edges, holes and curved areas.
- For precision-fit cut pieces, we account for the width of the laser cut.
- No simulated shadows or color effects.
- Simpler designs engrave more efficiently.

Please create artwork for laser engraving. Make it black-and-white line art only: pure black on a solid white background, with high contrast so it's obvious which parts get engraved. Use clean, smooth, closed shapes and solid lines, ideally in a crisp vector style, and avoid very thin lines and tiny details that a laser can't hold. Do not use color, gray tones, gradients, simulated shadows or photo effects. If the design needs texture or shading, use an engraving or woodcut style made of solid lines and dots instead of gray. Keep large solid black areas to a minimum. Keep the design simple enough to engrave well on the item and material, and leave a clear margin around the edges. Center the design, with no mockup and no words unless I ask for them, and make it as large and sharp as possible. My design:
For example, after “My design:” type: a pine tree and mountain scene for a wooden cutting board, in an engraving style with line shading.
Promotional products (pens, mugs, bags)
What works best: A simple 1- or 2-color logo that still reads when it’s tiny.
Pens, mugs, tote bags and other promotional products usually have a small imprint area, especially pens. Simple 1- or 2-color logos that stay bold and readable when they’re shrunk work best.
✔ Do
- Keep it to 1 or 2 solid colors.
- Use a simple, bold mark that reads at small sizes.
- Test it: zoom out until it’s about the size of your thumbnail. If you can’t tell what it is, simplify.
- Ask for a wide, compact version if it’s going on a pen.
✘ Don’t
- Use fine details, thin lines or small text.
- Use gradients or photos.
- Crowd the design with taglines and extra words.

- 3. Describe your design after “My design:”
Please create a simple logo for printing small on promotional products like pens, mugs and tote bags. Use only 1 or 2 solid colors and a flat, vector-style look with bold, thick shapes. It needs to stay clear and recognizable when it's shrunk to about the size of a thumbnail, so leave out fine details, thin lines, small text, taglines and extra words. Keep plenty of space between the shapes so they don't blur together when printed small. Do not use gradients, shadows, photos or 3D effects. Make the layout compact, and if it's going on a pen, make a wide, horizontal version. Use a plain white background, centered, with no mockup and no words unless I ask for them. Make it as large and sharp as possible. My design:
For example, after “My design:” type: a house with a key in dark blue, in a wide version that fits on a pen.
Signs, banners and stickers
What works best: Full color and high resolution, with background that runs past the edge.
Signs, banners and stickers can be printed in full color, so gradients and photo-style art are OK. Signs and banners are big, so resolution matters more here than anywhere else.
Many prints also need bleed: extra background that runs past the cut line so there’s no white edge after trimming. Die-cut stickers need a clean outline to cut around. We’ll confirm the exact size, resolution and bleed for your item on your proof.
✔ Do
- Tell the AI the final shape (a wide banner, a square or round sticker).
- Ask for the highest resolution it can make.
- Keep important art and words away from the edges.
- For die-cut stickers, ask for a thick, solid outline (often white) around the design.
✘ Don’t
- Put key details right at the edge, where they could be trimmed.
- Use small text on a big sign meant to be read from a distance.
- Let the AI write the words; send us your text instead.

Please create a full-color design for a sign, banner or sticker. Gradients and photo-style art are fine. Use bold, easy-to-read shapes that can be seen from a distance, and keep important art well away from the edges so nothing gets trimmed off. Let the background run all the way to the edges, and a little past them, for bleed, so there's no white edge after cutting. For a die-cut sticker, add a thick, solid white outline around the design and leave the background outside the outline transparent instead. Leave out any words, because they'll be set in a clean font later. Match the final shape I describe, such as a wide banner or a square or round sticker, and make it the highest resolution possible. Don't show a mockup. My design:
For example, after “My design:” type: a smiling cartoon taco for a square die-cut sticker.

AI art FAQ
Can I use an AI image as-is?
Sometimes. If it’s sharp, simple and uses the right number of colors for your decoration method, it may print well as it is. Most AI images need some cleanup first, like removing the background, cleaning up edges, cutting down colors or converting to vector. We check every file and let you know what it needs, and you’ll approve a proof before we make anything.
Will you fix or clean up my AI art?
Yes, our graphics team can help. We can remove backgrounds, clean up edges, reduce colors, vectorize your art and set your text in a clean font. Send us what you have and we’ll let you know what it needs when we quote.
Why should I leave text out of my AI image?
AI tools often misspell words or make letters that look almost right but aren’t. Ask the AI for no text, type your exact wording when you send your art, and we’ll set it for you. If your design already has AI text, check every letter carefully.
What file type should I send?
A vector file (AI, EPS, SVG or PDF) is best. Most AI tools make PNG or JPG files, and those work too. Send the largest version you have and we can vectorize it.
Who owns AI-generated art?
It isn’t always clear. The rules for AI-generated images are still changing, and they can depend on the AI tool’s terms and where you live. Check the terms of the tool you used, and don’t ask it to copy trademarked characters, logos or another artist’s work. This is general information, not legal advice. If ownership matters for your business, talk to a lawyer.
