work, a resolution of 200 - 250 dpi is generally acceptable. If the image has a lot of text

or hard edges, you should use a “final image size” resolution of 300 dpi.

If you are new to computer graphics, take some time to gain a good understanding of

image resolutions. It will dramatically improve the quality of your work.

Halftone Frequency, Angle and Shape

The Epson 7800 (FastRIP

XL), Epson 9800 (FastRIP

LF), and Epson 4000

(FastRIP

Pro) create an excellent halftone at a line count of up to 133 lines per inch

(LPI) using FastRIP

Standard Density 2880 and a round dot shape. As you get

higher than 133 LPI, slight banding may occur. This is due to the fact that at a printer

resolution of 2880 x 1440 dpi, a higher line count will produce more gray levels.

Note: The Epson 4800 can only print up to 65LPI.

FastRIP

does a good job of creating whatever dot shape you set. While it has been a

commonly held belief that an elliptical dot was better, you might find that with an inkjet

printer, round is a better dot shape choice.

When printing halftone dots on or next to halftone dots, optical patterns can form called

“Moiré Patterns.”These patterns look like checker boards and are not desirable. To

minimize Moiré Patterns, use a halftone angle of 25 degrees for all screens on

photorealistic jobs. This is called “Simulated Process Color.”For normal CMYK Process

Color, try angles of Cyan 15, Magenta 45, Yellow 75 and Black 75 (Yes, the black and

yellow are the same angles.)
