    Is Anyone Running to CGATS.21-2 CRPC-3?

    I'm just curious if anyone has implemented this in the pressroom and is using it daily. If so, does it look like it has enough contrast? I have not implemented it, but early testing looks like photographs need adjustments. Pressman have traditionally ran more ink than is required by the...

    When to use ∆E2000 vs ∆Eab

    My understanding is ∆E*ab for offset process work, measuring primaries and overprints and ∆E2000 for press to proof, PMS, and digital print evaluation. I use Heidelberg's color management suite, so I reached out to them to ask their opinion. They said what I said above. Maybe because their...

    Inking Series, vary density across zones. CP2000 with XL105

    I'm looking for a PDF based manual for the Heidelberg CP2000 console. I'm trying to run what I've heard called an "Inking Series". Basically, vary the amount of ink across the zones so one can find the best wet standard aims possible to match dry standards. What I don't know is if this is...

    GRACoL2006 M2 Numbers

    We have a Heidelberg Image Control, and as far as I can tell, it scans in just one mode. I talked with Heidelberg and they say it scans in M2. I would like to put the GRACoL 2006 numbers in there for M2 as a reference for the pressman to use on coated stocks, but don't know what they are or how...

    Paper White M1 and M0 Differences

    We currently don't have an M1 spectrophotometer. I'm looking into changing our proofing paper for one with a white point closer to GRACoL 2013. I have received a sample roll from a vendor that is supposed to be the white point for 2013. When I measure its white point in M0, I get -3 in b*. I'm...

    Processor Getting Louder

    We have a Glunz & Jensen CP 85 Processor that is producing a rumbling noise when it processes a plate. You only hear it when a plate is processing. If you run a rinse cycle with no plate, it's not there. Also, the steady cycling sound of it's normal process seems to be getting louder and not...

    Solid Ink LABs - GRACoL 2006 & GRACoL 2013

    Hello, I'm currently evaluating our solid ink LABs. I have received a certificate of analysis and compliance from our ink manufacturer that states it's in compliance with ISO-2846-1 as directed in ISO 12647-2. Right now, when referencing GRACoL 2006 and averaging 10 it8s, measured with an...

    Epson Inline Verification

    I'm having a problem with my Epson 9900 with attached X-Rite SpectroProofer cutting the sheet after it scans and verifies it. I can manually go over and perform a cut operation on the proofer itself, but the proofing sequence used specifies that it's to cut the media. This only happens when...

    Color Toolbox (Dry > Wet Standard)

    I've been working my way through Color Toolbox, trying to implement these fancy color tools that we're not taking advantage of. I'm trying to create a "Wet Process Standard" in the "Process Standard" tap. In the help file for this section, he says to use a CS4i or FOGRA4 control strip. It also...

    Color Toolbox

    I'm starting to use Color Toolbox for the first time. I'm trying to get our color management under control, etc. I have an X-Rite Eyeone iSis that I've used to measure an IT8.7-4 Random target that I've outputted from a proofer. I'm getting a few messages that I don't understand. The first is...
