A color bar is the color strip on proofs that is used as a guide for the printer to determine the amount and density of ink needed. A color bar is a standard used to compare color accuracy of an image for output; color bars are printed on proofs and forms to maintain color consistency.
Rows of color patches printed in the trim area used by printers to check color accuracy and density
Quality control mechanism consisting of small strips of color and patterns on press sheets. Used to check color registration, dot gain, ink density and evenness.
A series of colored squares printed off the edge of a page. These color squares are used to verify the accuracy of the film used to make printing plates, and are used by a press operator to help calibrate the printing press. Progressive color bars are color bars which run along the entire edge of an imposed flat, and are used to verify correct color on press.
A series of solid rectangles on a film which are shot on each plate. These are used to set and control ink densities on press.
A tool used to judge color accuracy of an image when shooting film for output.
A quality control term regarding the spots of ink color on the tail of a sheet.
Most glass color come in the form of bar. The major manufacturers of glass color bar are Reichenbach, Kugler, Zimmerman and Gaffer. The process of making these involves adding metal oxides and other toxic ingredients to crucibles of molten glass, and then pulling the glass out and rolling it into bars.
A strip of small blocks of color on a proof or press sheet to help evaluate features such as density and dot gain. Also called color control bar, color guide and standard offset color bar.
Strip of colors printed near the edge of a press sheet to help evaluate ink density.
In film post-production, an electronically generated set of colors used as a visual reference standard.
