Shortly after in 1994, Epson released the first 720 dpi colour inkjet printer, the Epson Stylus Color (P860A) utilizing the Micro Piezo head technology. Newer models of the Stylus series employed Epson's special DURABrite ink and used two hard drives (an HD 850 and an HD 860). [15] Epson R2000 printer
When printing at 150 lpi, traps are usually between 1/150 and 1/300 inch (0.48 pt and 0.24 pt, 0.16 mm and 0.08 mm). These values are usually multiplied by 1.5 or 2 when one of the colors is black. The trap is not visible since the lighter color is spread underneath the—almost—opaque black.

Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. [1] Inkjet printers were the most commonly used type of printer in 2008, [2] [needs update] and range from small inexpensive consumer models to expensive professional machines.
In printing, under color removal (UCR) is a process of eliminating overlapping yellow, magenta, and cyan that would have added to a dark neutral (black) and leaving the black ink only, called a full black, during the color separation process. Under color removal is used in process color printing.
Although a combination of 100% cyan, magenta, and yellow inks would, in theory, completely absorb the entire visible spectrum of light and produce a perfect black, practical inks fall short of their ideal characteristics, and the result is a dark, muddy color that is not quite black. Black ink absorbs more light and yields much better blacks.
The aim of color calibration is to measure and/or adjust the color response of a device (input or output) to a known state. [1] In International Color Consortium (ICC) terms, this is the basis for an additional color characterization of the device and later profiling. [ 2 ]
