Colors

The Colors section governs how color is described in the PDF — the single biggest factor in whether print output matches what the customer saw on screen. Each check lists its action, settings, and the messages the customer sees. See the profile overview for how actions work.

Document Color Mode

Which color modes are allowed in the document (e.g. CMYK, Grayscale). During auto-fix, “Convert all” converts any color space — including images and text — to an allowed one.

Field	Detail
Action	Auto-fix
Settings	Allowed (CMYK / Grayscale / RGB / Lab), Convert all, Preserve during auto-fix (ICC, DeviceN, NChannel, Separation, Separation All)
Issue	Your file contains `{actual.found}` colors, but we require files to be in `{target.allowed}` color mode only.
Fix	Convert your document to `{target.allowed}` and re-upload.
Auto-fix	We’ll convert your colors to `{target.allowed}` automatically before printing.

Maximum Ink Coverage

The total ink coverage (TAC) limit, to prevent smearing or slow drying on press.

Field	Detail
Action	Warn
Settings	Maximum (%, default 300)
Issue	Some areas use too much ink (`{actual.percent}`%), which can smear or dry slowly. The limit for this product is `{target.percent}`%.
Fix	Reduce the density of your darkest areas and re-export.

Spot Colors

Whether spot (named) colors like Pantone are allowed, and how many.

Field	Detail
Action	Warn
Settings	Max count, Whitelist (e.g. `PANTONE 186 C`)
Issue	Your file uses `{actual.count}` spot colors (`{actual.names}`), but this product requires `{target.max_count}` spot colors maximum.
Fix	Convert the excess spot colors to CMYK and re-upload.

Output Intent

Require an embedded output intent (color profile) that defines how the file’s colors should print.

Field	Detail
Action	Warn (can auto-fix)
Settings	Expected ICC profile
Issue	Your file is missing a color profile that tells us how to reproduce its colors accurately.
Fix	Re-export with an embedded output intent (color profile) and upload again.
Auto-fix	We’ll add the expected color profile automatically before printing.

ICC Color Profile

Control which embedded color profiles are accepted.

Field	Detail
Action	Warn (can auto-fix)
Settings	Whitelist (profile names)
Issue	Your file uses a color profile we don’t support.
Fix	Re-export using a standard print color profile and upload again.
Auto-fix	We’ll convert it to a standard print profile automatically before printing.

Rich Black

Detect black text or elements built from all four inks instead of pure black (K), which can look blurry on press.

Field	Detail
Action	Auto-fix
Settings	Scope (Text only / All elements)
Issue	Some black text is built from all four inks, which can look blurry on press. It should be 100% black (K) only.
Fix	Set the affected black to 100% K only and re-export.
Auto-fix	We’ll set the affected black to pure K automatically before printing.

Overprint Settings

Detect overprint flags that may cause elements to disappear on press.

Field	Detail
Action	Warn
Settings	Reject overprint on white (toggle)
Issue	Your file has overprint settings that may cause some elements to disappear when printed.
Fix	Check the overprint settings in your design app and re-export.
