Line printer for the digital output and colorimetric measurement of colored images
First Claim
1. A color measuring system having a line printer for the digital output and colorimetric measurements of colored images, comprising:
- a housing;
a paper feed means for feeding paper to the line printer;
a paper discharge means for receiving paper from the line printer;
a printer carriage with a printing head and a flexible cable, wherein the printer carriage is movable in a direction transverse to the paper feed means;
a transporting roller for the paper feed means;
a printer controller for controlling the line printer; and
a color measuring head with a light source and a measuring aperture oriented toward a measuring surface, the color measuring head arranged to be fixed to the printer carriage in lieu of or in addition to the printing head, wherein the color measuring head measures reflection from the light source off paper passing over the measuring surface and is in communication with its amplifying, control and evaluating electronic units arranged inside or outside the line printer.

Abstract
The present invention is concerned with a line printer for the digital output and calorimetric measuring of colored images, comprising a housing, a paper feeder, a paper discharge means, a printer carriage movable in a direction transverse to the paper feed plus printing head and flexible printer cable, a transporting roller for the paper feed and a printer controller for the control of the printing functions. To enable a line printer of the afore-described type to be used not only for its inherent printing function but also for colorimetric measurements and for computing and using the color profile, to thereby automate the color characterizing process and to free the user from using manual and error-susceptible designs containing a color measuring instrument of the conventional type, in the practice of the invention, a color measuring head for reflection measurements is arranged to be fixed to the printer carriage in lieu of or in addition to the printing head, with the said color measuring head with the measuring aperture thereof being oriented toward the paper passage plane and being in communication with its amplifying, control and evaluating electronic units arranged internally or externally of the printer.
