    Indigo 3500 HDI (2400x2400)

    We have a request to print an job on our Indigo but it must be done at 2400x2400. We see that we have a license for what HP refers to as HDI, High Definition Imaging, A.K.A. 2400 x 2400. Does anyone one know how to enable it? Also can I go with "tiff out" of Apogee Prepress and drop them in an...

    Preps Question

    I've got 40 pages that I need to impose such that they get cut down to two-up and collated and then will cut and stack. I have a 32 page W&B form and also an 8 page 2-up, 4-out W&T. When I select cut and stack and number the pages for form 1 (32pager) I pair 1 and 17, 3 and 19, 5 and 21 . . . ...

    Plate Grain Direction

    I understand the crimping/cracking issue with web. And I understand that the metal has a grain direction. But isn't there additional graining or treatment done to the surface that allows the plate to carry water? It would seem to me that it would be better to have surface graining run across...

    Blinding problem

    We had this problem with these plates on sheetfed presses. AGFA rep said that the developer replenishment was critical. The development process is some sort of silver diffusion process and if the temp/time/activity of the developer is not optimal then we got blinding. The silver has to "go down"...

    Plate Grain Direction

    What is the importance/significance of the plate grain direction. I've always thought the grain should run across the cylinder. Our Kodak plates are running around the cylinder. We have a print problem that evidences itself in the top half of the tone scale that look suspiciously like the grain...

    Considering a 29 - any advice appreciated

    Several years ago we traded in a 640 and a 628 Akiyama for 629 and 429 ManRolands with coaters. I think losing 40" capability was a mistake. Also, we find ourselves throwing a ton of paper away since you often have to buy 23x35 and cut it down since many papers do not come 23x29. 6-up letter...

    Press fingerprinting: SID absolute or relative

    Isn't running the NPDC a major part of "fingerprinting" a press? Which is what the OP was asking about. And then all the replies came back "absolute" for North America, hence my observation;~) Clark

    Press fingerprinting: SID absolute or relative

    Question then: As I look at the G7 NPDC graph paper I notice that a 2% dot should yield about a .02 density. Most of the papers I read have a density higher than this(~.05). So if I add a 2% printing dot on there I'll be well over the suggested .02 more like .07-.09. How do we reconcile this...

    Round vs Euclidean

    Sorry if slightly OT but 2400 vs 2540 and screening Sorry if slightly OT but 2400 vs 2540 and screening Interesting discussion on dot shape and someone brought up the issue of 2540 vs 2400. My question is what happens when the front end RIPs at 2400 but the native resolution of the device is...
