Hi all. While printing one job we noticed that a moire effect was very evident for the whole sheet. Both press and prepress guys agreed that it was the magenta plate causing the moire.
We print our plates from our old Apogee v3.0 with 175lpi/2400 dpi, Elliptical Dots. Our angles used are C15 M75 Y0 K45 (Agfa Balanced Screening). Also in the Apogee, under the Screen-Render tab the "Use Single Settings for All Content" is Checked and under the Screen tab the "Fixed Screen" is Checked. Our CTP is Galileo and we use positive Silver plates.
We got our ccDot plate reader and measured the color bar of the Magenta plate, as well as some screen tints in the image area. Measurements revealed 163lpi and the angle is 15 degrees.
We're confused since the Agfa Balanced Screening setting for Magenta is 75 degrees and we printed the plate at 175lpi...and not 163lpi. Now we have both the Cyan and Magenta plates both at 15 degrees.
We're hoping someone could shed some light.
Thanks.
