Barra colore

Le barre colore forniscono un riferimento target che gli operatori di stampa usano per monitorare la densità dell'inchiostro, l'incremento del punto e la coerenza del colore lungo tutta la tiratura. Le barre includono patch dei colori di processo (CMYK), target di registro e campioni facoltativi di tinte piatte.

Options Guide
Location

Position the color bar along a page edge using the selection grid.

Choose which edge of the page receives the color bar. The bar runs along the full length of the selected edge, positioned just outside the trim boundary.

Marks

Configure mark size, spacing, and repeat behavior.

Size controls how large each color patch appears. Repeat fills the available edge length with repeating bar patterns for more measurement points across the sheet.

Colors

Select which color patches to include in the bar.

Standard bars include CMYK process patches. Spot colors adds extra patches for any Pantone or custom inks defined in the document. Registration patches help verify plate alignment.

Shapes

Choose the shape of individual color patches.

Squares are the most common and easiest to measure with a spectrophotometer. Circles and rectangles are available for specific press proofing workflows.

Configurations & Variations
Color Bar at Bottom Edge

Select the bottom position in the location grid. The CMYK control strip is placed along the bottom sheet edge with individual color patches separated by a thin gap for clean densitometer readings. Bottom placement is standard when the top edge is the gripper (the non-printable zone held by press grippers). Each patch in the strip (Cyan, Magenta, Yellow, Black, plus overprint combinations) must be wide enough for your spectrophotometer's aperture, typically 4-5 mm minimum.

Expert Tip

On offset presses, place colour bars along the gripper edge for inline densitometry. On digital presses, place them on the trail edge where toner coverage varies more.

Colour bars increase the overall sheet dimension. Verify your press sheet has enough non-image area to accommodate them without clipping.
