The DTF halftone action, right in your browser
An exact clone of the Half Tone 300 DPI Photoshop action, grown into a full prep station: the real Levels dialog with eyedroppers, a fades-and-shadows mode for soft art, screen and dot-shape controls, white underbase export, and a 30 percent minimum-dot rule so every dot holds on fabric. Nothing leaves your device.
The Photoshop action, dot for dot
DTF Engine runs the same pipeline as the Half Tone 300 DPI action that print shops use to prep DTF artwork: it measures how far every pixel is from the shirt color, runs that through your Levels move, and rasterizes the result as a 35 LPI round-dot screen that matches Photoshop's output dot for dot. Tones near the shirt color dissolve into dots and drop out; tones far from it print solid.
The output is what your press wants: a transparent PNG with hard 1-bit dots (no half-transparent pixels to muddy the white underbase), your original colors untouched under the screen, and the 300 DPI resolution written into the file. Tested against real outputs of the action itself, the result matches 97 to 99% of pixels, dot for dot.
Starting from a small or low-resolution file? Run it through Upscale Engine first to reach print size at 300 DPI, then bring it here for the halftone.
Nothing is uploaded
There is no server behind this page. Your artwork is read, screened, and saved entirely on your own device, which is why it works with client files you could not legally upload to a random website.
That is also why it is free with no accounts, credits, or watermarks. There is no GPU bill to pass on to you.
