A Raster profile checks standalone image uploads (JPEG, PNG, TIFF, WebP) — not images embedded inside a PDF, which are covered by the PDF Images section. Raster checks focus on whether the image is big enough, the right shape, and in a print-ready color mode. Many can auto-fix using AI and image transforms. Each check lists its action, settings, and the messages the customer sees; see the profile overview for how actions work.

Effective Resolution

The minimum resolution at the target print size, with optional AI upscaling to meet it. Effective DPI = pixel size ÷ target print size.
FieldDetail
ActionReject (can auto-fix)
SettingsMinimum (dpi, default 300), Print width (mm), Print height (mm)
IssueYour image won’t be sharp at the required print size. It works out to {actual.effective_dpi} DPI, but we need at least {target.min_dpi} DPI.
FixUpload a higher-resolution image so it reaches at least {target.min_dpi} DPI at print size.
Auto-fixWe’ll AI-enhance your image to the required resolution automatically before printing.

Minimum Pixel Size

The smallest acceptable dimensions in pixels. Auto-fix uses AI to upscale smaller images.
FieldDetail
ActionAuto-fix
SettingsMin width (px), Min height (px)
IssueYour image is smaller than required. You uploaded {actual.width} × {actual.height} pixels, but we need at least {target.min_width} × {target.min_height} pixels.
FixUpload a higher-resolution image, at least {target.min_width} × {target.min_height} pixels.
Auto-fixWe’ll enhance your image to the required size automatically before printing.

Maximum Pixel Size

Flag images larger than needed. Auto-fix reduces oversized dimensions.
FieldDetail
ActionWarn (can auto-fix)
SettingsMax width (px), Max height (px)
IssueYour image is larger than needed ({actual.width} × {actual.height} pixels), which may slow processing without improving print quality.
FixResize your image down and re-upload.
Auto-fixWe’ll resize your image down automatically before printing.

Color Mode

Which color modes are accepted (e.g. CMYK, Grayscale, RGB).
FieldDetail
ActionAuto-fix
SettingsAllowed (CMYK / Grayscale / RGB / Lab / Indexed)
IssueYour image is in {actual.colorspace} color mode, which isn’t suitable for this product — we require {target.allowed}.
FixConvert your image to {target.allowed} color mode and re-upload.
Auto-fixWe’ll convert your image to a print-ready color mode automatically before printing.

Bit Depth

The minimum color bit depth required to avoid banding.
FieldDetail
ActionAuto-fix
SettingsMinimum (1 / 4 / 8 / 16 bit, default 8)
IssueYour image has low color depth, which can cause banding. Use {target.min}-bit or higher.
FixRe-save your image at {target.min}-bit or higher and re-upload.
Auto-fixWe’ll increase the color depth automatically before printing.

Transparency

Allow a transparent background, or flatten it to a solid color.
FieldDetail
ActionAuto-fix
SettingsAllow transparency (toggle)
IssueYour image has a transparent background.
FixFlatten the transparent background and re-upload.
Auto-fixWe’ll flatten the transparency automatically before printing.

Background Removal

Automatically remove the background from the uploaded image.
FieldDetail
ActionAuto-fix
SettingsNone
IssueThis product requires an image without a background, but your image appears to have one.
FixRemove the background from your image and re-upload.
Auto-fixWe’ll attempt to remove the background automatically before printing.

Maximum File Size

The largest file customers may upload.
FieldDetail
ActionReject
SettingsMax size (MB, default 50)
IssueYour image file is too large. The limit for this product is {target.max_mb} MB.
FixReduce the file size and try uploading again.

ICC Profile Required

Require an embedded color profile to keep colors consistent on press.
FieldDetail
ActionAuto-fix
SettingsExpected profile (any ICC profile, or a specific one)
IssueYour image doesn’t include the required {target.expected_profile_name} color profile, so colors may shift when printed.
FixEmbed the correct color profile when saving your image and re-upload.
Auto-fixWe’ll embed the expected color profile automatically before printing.

Aspect Ratio

Restrict image proportions. Auto-fix pads or crops the image to the required ratio.
FieldDetail
ActionAuto-fix
SettingsRatio, Tolerance
IssueYour image isn’t the right aspect ratio ({target.ratio}) for this product.
FixResize your image to {target.ratio} and re-upload.
Auto-fixWe’ll resize your image to the correct shape automatically before printing.

Total Ink Coverage

Limit total ink coverage (TAC) to prevent print defects.
FieldDetail
ActionOff (can auto-fix)
SettingsMax TAC (%, default 300), Convert to profile (ICC)
IssueYour image has too much ink in some areas ({actual.max_percent}%), which can cause print defects. The limit is {target.max_percent}%.
FixReduce the total ink coverage and re-export.
Auto-fixWe’ll reduce the ink coverage automatically before printing.
