White underbase

Set the white underbase for your DTF sheet.

Choose 0, 1 or 2 px choke for the whole sheet. NestSheet applies that choice to the exported W1 channel and uses thin-detail protection during white generation.

Start your first sheet See the full workflow

NestSheet sheet in the Art + White view, the colour artwork over its white underbase, with White 2 px choke in the top bar — Art + White: the artwork over its white underbase; the sheet’s choke, 2 px, sits in the top bar.

White edges

Bring the white edge inside the colour.

Choke draws the white edge inward. Inspect source transparency, white coverage and colour-to-white alignment as separate parts of the print check.

The production workflow derives the white underbase from the PNG artwork’s alpha.
Choose 0, 1 or 2 px in the White control. The selected value applies to the whole sheet.
The default is 2 px. Compare settings on the same artwork at the same final print size.
Inspect the exported W1 channel to judge the final white edge and fine details.

Normal view of a sheet section: the colour artwork of the designs — Normal: the artwork as it prints in colour.

White only view of the same section: each design's white coverage in white on dark grey — White only: the white coverage, shown before the export choke. Check the final edge in the exported W1.

Canvas inspection

Read the artwork in four views.

Normal, White only, Art + White and Fabric give you different ways to inspect the artwork and its coverage.

Normal shows the artwork for layout review.
White only shows the canvas white-coverage view before export choke is applied.
Art + White combines the artwork and white inspection layers.
Fabric places the artwork against a selected fabric colour for visual inspection.

Small details

Check fine lines at their print size.

White generation includes a rescue step for qualifying thin details that choke would erase. Review small lettering and isolated dots in the final separation.

Set the design’s physical size before comparing choke settings.
Keep a fine-line sample, small text and a solid shape together in a controlled test sheet.
Use the exported W1 and a small print to approve the result for your material and queue.

In the file

The selected choke reaches the print file.

The export dialog names W1 and shows the chosen choke for the whole sheet. The Production DTF preset writes a mirrored 300 dpi TIFF with CMYK and one W1 white channel for MainTOP. Read the export specifications, then inspect that file in the receiving queue.

FAQ

The questions operators actually search.

Why is there a white outline on my DTF print?

A white halo is white ink visible beyond the intended colour edge. Inspect the PNG transparency first, then the exported white separation and the colour-to-white alignment in the RIP. NestSheet lets you choose a 0, 1 or 2 px choke for the whole sheet. Approve the result with the job at its final size.

What choke setting should I use?

NestSheet starts at 2 px and offers 0, 1 and 2 px for the whole sheet. Compare these settings with the same artwork, final dimensions and MainTOP queue. Look at solid shapes, fine strokes and small text in the exported W1 channel, then choose the setting that passes your shop’s print check.

What does the White only canvas view show?

White only is a canvas coverage view based on the artwork before export choke is applied. Use it to inspect where the white backing is expected across the sheet. To judge the final inset and thin details, export the Production DTF preset and inspect its W1 separation in MainTOP at the intended print size.

How do I fix a dusty white halo?

A dusty halo is adhesive powder bonding where faint edge pixels receive white: anti-aliasing, glow or background-removal residue. NestSheet derives white from the PNG alpha with a fixed threshold, so clean the faint pixels in the source artwork and export a fresh transparent PNG. Then compare 0, 1 and 2 px choke and inspect the exported W1 separation in MainTOP at final size.
