The GUI is the Graphic Unit Interface, is the monitor that operator uses at the press itself. You select various menus such as Job Selection Imaging, Inking etc via the Trackball (mouse). Sometimes the ability to move from menu to menu on the screen can be slow. This is why I say deleting ink profiles and stored jobs can speed up the operation of the GUI. You have the capability to image from the press computer itself, if you download the jobs from the RIP to the press computer. Normally you would image jobs directly from the RIP. The Rip is usually stationed in the pre-press department. If you have a screen saver on the RIP, get rid of it. It can slow down the transfer of Data from the RIP to the press. (Trust me I saw it happen) Also early DI presses and DI Plus models had 486 computers and later it was Pentiums. If you started with a Pentium and it failed under warrant,y they would replace it with whatever was available ie. it could have been another 486. I was once involved with installation that used a Scitex RIP. However it could not send an ink profile to the press, The operator had to use the Ink Calculation function that was on the Inking Gui menu. Hope some of this information is of some help.
