Screen print — raster + halftones + gradients
This page is for jobs with photos, gradients, and soft blends.
We can print photorealistic work — if the file is built correctly.
The rule
Do not send pre-halftoned/bitmapped art.
Send tones as channels. We generate halftones in our RIP so we can control dot gain and generate optimized output.
Preferred file types (when you’re not separated)
Best → worst: 1) PSD (preferred) 2) TIFF 3) PNG 4) JPEG (last resort)
Resolution
- 300 DPI (or higher) at print size
- Don’t send tiny art and expect miracles. The print won’t be better than the pixels.
Transparency + cleanup
- Use transparent backgrounds whenever possible
- Remove “almost invisible” noise
- Watch for stray 1% dots — they can print
- Use the color picker / channel view to confirm true zeros (background should be clean)
Grayscale: use Multichannel
For grayscale photos:
- Convert to Multichannel (not Bitmap)
- Adjust with curves/levels as needed
- Let our RIP handle the halftone conversion
Color channels (sim process style)
If you’re building channel seps:
- Keep channels editable (don’t convert to halftones)
- We handle dot gain in the RIP
- If you need unusually high fidelity, call it out before production
Illustrator + Photoshop workflow (recommended)
If you’re combining raster + vector:
- Put vector elements + spot color labels + reg marks in AI
- Keep the raster channels in a linked PSD in the same zipped folder
- Always place and link -- 8 bit color composite -- single file
- Don’t embed giant raster files into AI
LPI (when to mention it)
You do not need to specify LPI unless you need higher than 55 LPI.
If you have a special case, tell us in the job notes.
Print order
If the job needs a specific print order, call it out in job notes, otherwise we’ll use our discretion.
Photos, gradients, and “soft art” are absolutely doable — they just need different handling than spot vector art.
This page covers what we need so it prints the way your proof shows.
Minimum requirements
- Provide raster art at final print size
- Aim for 300 DPI at size (higher is fine)
- Avoid tiny images scaled up
- Avoid screenshots
- Avoid heavily compressed JPEGs when quality matters
How we prefer to handle raster separations
If you want clean control over a photo/gradient separation:
- do the separation work in Photoshop (multi-channel workflow)
- place/link into Illustrator for registration marks + labeling + template alignment
The RIP reads the Illustrator file, but we can adjust the tonal curves in Photoshop without rebuilding everything.
If you don’t have this workflow, that’s fine — just send the best source file you have and we’ll guide you.
Halftones
If your art uses halftones:
- call out the LPI (lines per inch) you want, if it matters
- plan for dot gain (what looks perfect on screen may fill in on press)
- make sure the proof reflects what you want to see printed
Proofs must match reality
With raster art, the proof matters even more.
If your proof shows detail we cannot physically hold on press, we’ll flag it before production.
