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...

Thanks, this is exactly what I've been waiting to hear.

Lol, I have some questions to go with this. Will my current Spectro Proofer 44" with ILS20 attach to the new Epson SureColor P9000? I'm pretty sure this is true, but am not certain. http://www.colorhq.com/Epson-SpectroProofer-Replacement-p/c12c932021.htm

A process standard based on spectral data is setup on a scanning device that scans the color bar or image area, like an Image Control or IntelliTrax. The standard has been determined as achievable with the stock+ink combination during process calibration long ago. Pulls are made as the press is...

Thanks so much for the feedback. Is this for digital and offset?

I told you wrong earlier on the cyan move. I was responding during intermission at a hockey game, so that's my excuse.:D Here is a document that helped me see how LAB moves. It was provided to move from Heidelberg as a scan a long time ago, but I have cleaned it up, so it may help someone else...

You know, I don’t even know a response to this. I really don’t want to try and teach on this forum. Obviously you guys have no experience with my original question. To continue this debate, modern software and devices easily make these moves for the pressman. There is nothing complicated about...

You’re right, there is only so much control they have, but they have some. It’s all GRACoL in my shop and it’s very achievable. If they can’t do anything about hitting the standard, maybe it’s an unrealistic standard. In my experience, the LABs move in one pretty consistent, predictable way in...

In my opinion, the pressman should use both, and understand how one effects the other. The pressman, to an extent, does have control over the solid LABs, via density moves. As long as the LAB aims established for the ink+stock combination are within the printable SIDs. The process standard...

I understand this. My question is still: What is your opinion on this? What are you doing in your shop? and why do you think this way?

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...

I'm not confusing silks and synthetics, I'm asking for anyone to list any TAC they are using for any stocks. I'm currently using 300% for silk. I have specs on 1 synthetic stock, Polyart. It states 260%. I'd just like to know what others are doing for any stocks.

Something I didn't mention above, I'm talking for sheetfed offset, no waterless or UV. I used to think the same way, then I received some specifications for Polyart paper, which is considered a synthetic, something I plate with a coated TVI curve. The specifications call for a max TAC of 260%...

If anyone would like to share, I'd like to know what TAC percentage you are using for different papers. Specifically silk papers. Let me know what brands, finishes, and weights. Thanks

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...
