Color management

Introduction

HP Designjet T1100 printers have been engineered with advanced hardware and software features to ensure predictable and dependable results.

●Color calibration for consistent colors.

●One gray and two black inks provide neutral grays on all paper types.

●The Photo Black ink provides pure blacks when printing on photo papers.

●Color emulation of other HP Designjet printers.

How colors are represented

All devices that display color use a color model to represent color in numerical terms. Most monitors use the RGB (Red-Green-Blue) color model, while most printers use the CMYK (Cyan-Magenta-Yellow- blacK) color model.

An image can be converted from one color model to another, but in general the conversion is not perfect. Your printer uses the RGB color model: the same color model that is used by your monitor.

This simplifies but does not completely solve the problem of matching colors. Each device represents colors a little differently from another device, even if they use the same color model. However, software can adjust the colors in an image according to the characteristics of the particular device, using a color profile of the device, in order to achieve correct colors.

A summary of the color management process

To get the accurate and consistent colors that you want, you should follow these steps for each paper type that you use.

1.Color-calibrate the paper type, for consistent colors. Calibration should be repeated every now and then (see Color calibration on page 74). In addition, you may wish to calibrate immediately before a particularly important print job for which color consistency is vital.

2.When printing, select the correct color profile for the paper type you are using.

Color calibration

Color calibration enables your printer to produce consistent colors with the particular printheads, inks, and paper type that you are using, and under your particular environmental conditions. After color calibration, you can expect to get similar prints from any two different printers situated in different geographical locations.

Some paper types cannot be calibrated. For all other paper types, calibration should be done in any of the following circumstances:

●Whenever a printhead is replaced

●Whenever a new paper type is introduced that has not yet been calibrated with the current set of printheads

●Whenever the environmental conditions (temperature and humidity) change significantly
