Vecspine screens your vector artwork and raster photos into true AM halftones. CMYK separations with rosette angles, single-screen grayscale for photo tees, white-ink invert, 1-bit TIFF film positives and a multi-page press PDF. No moiré, no tracing required, no subscription.
Every channel is screened with its own angle and an area-calibrated dot, so printed coverage matches your artwork — not an approximation.
C 15° · M 75° · Y 0° · K 45° — the standard offset set that interlocks dot grids into a stable rosette instead of moiré.
No tracing required. Screen raster photos directly into single-spot grayscale for photo tees or full CMYK rosettes. Includes white-ink invert and physical print-width scaling.
Dot area equals ink coverage at every cell, so 50% tone prints as 50% ink — predictable on press.
Round (default), square, diamond and line ruling — pick the dot that suits the garment, mesh and ink.
Uncompressed 1-bit TIFFs (BlackIsZero) at 300/600/1200 DPI — exactly what exposure units expect.
Band-processed screening keeps RAM bounded even at 1200 DPI on large artwork — no crashes on big jobs.
Each CMYK channel is screened at its own angle so the dot grids interlock into a stable rosette pattern.
Trace a vector logo or drop a raster photo. Vecspine handles both vector CMYK plates and direct image halftones for photo tees.
Pick 25–200 LPI, a dot shape, and 300/600/1200 DPI in the Halftone dialog. Rosette angles are applied automatically.
Write one 1-bit TIFF per channel plus a multi-page PDF — named with channel, angle, LPI and DPI for the press.
Rough guides — always confirm with your printer, but these are safe starting points.
| Job | LPI | Notes |
|---|---|---|
| Dark garments / coarse mesh | 25–35 | Big open dots, forgiving on stretch |
| Standard textile | 45–55 | The default sweet spot |
| Paper / card stock | 65–85 | Finer detail, tighter mesh |
| High-detail / offset-style | 100–200 | Use 1200 DPI output |
25–35 LPI for dark garments and coarse mesh, 45–55 LPI for standard textile, 65–85 LPI for paper, 100–200 LPI for high-detail work. Vecspine lets you dial 25–200 LPI and always confirm with your printer.
Each CMYK screen is offset (C 15°, M 75°, Y 0°, K 45°) so the dot grids interlock into a stable rosette pattern instead of producing moiré.
A pure black-and-white raster where every pixel is either ink or no-ink — exactly what a screen exposure unit needs. Vecspine writes uncompressed 1-bit TIFFs (BlackIsZero).
Round (default), square, diamond and line ruling — all area-calibrated so printed dot area equals ink coverage.
Yes. The Image Halftone tool screens raster images directly — no vectorization required. Use Grayscale mode for single-screen photo tees, or CMYK mode for full-color process prints. You can even invert the output for white-ink prints on dark garments.
Yes. Screening, separation and export all run locally. Nothing is uploaded, ever.
Rosette angles, area-calibrated dots, 1-bit positives — offline, in one click.
