Vectors for
screen printing.

Why screen printers want vector art

Screen printing applies one ink color per screen. To make screens, the printer needs the artwork split into color layers with crisp edges. A low-resolution PNG makes that difficult, since fuzzy edges produce rough screens and uneven prints. A vector gives hard edges at any size. Vetorly rebuilds your image as real shapes with smooth Bézier curves and few nodes, and each color is a separate editable shape, which is a convenient start for separations.

Spot color designs versus full-color images

Designs made of a few flat colors, such as logos, band shirts and team graphics, are ideal. Artwork with soft shadows, glows or photo content needs a different approach, such as halftones or simulated process separations. A vector trace turns gradients into banded flat areas, which can look intentional but changes the design.

Prepare the image

• Reduce to the number of colors you can afford to print.
• Remove glows and soft shadows that you do not want turned into bands.
• Use the largest file you have, and avoid JPG compression when you can.
• Keep fine lines thick enough to hold on the screen mesh.

Checks for separations

1. Select each color and confirm it is one clean object, then note the count of colors.
2. Look for overlaps. Printers often want a slight overlap or trap so colors do not leave gaps if registration shifts. Ask what your shop prefers.
3. Check small details and gaps against what your mesh can hold.
4. Assign spot colors in your design software if the printer matches ink to a swatch book.
5. Remove the background shape so it does not print as a solid block.

What about DTF?

DTF and similar transfer methods print the design digitally, so gradients and many colors are less of a problem. A vector still helps because edges stay sharp at the size you print, and you can resize without quality loss. If your DTF workflow needs a raster file, the high-res PNG included with each credit can serve as the clean output.

Common mistakes

Enlarging a small file before printing, leaving off bleed or margin, and sending artwork with unwanted background boxes are the usual culprits. To prepare a brand mark for any printing job, see logo to vector. For a similar color-by-color approach in stitches, visit vectorize for embroidery.
