Save a sample from the first run and use that on the second run. Call it a "Brand Standard". This becomes the target for all subsequent runs. If you want to get scientific, create a label and write the densities and dot gains on the back, have the press operator sign and date. Press trending is...

I think everyone is wrong... :-) The question is what do you do in your standard file-to-plate-to-press workflow? Do you convert all files into one standard colour space? If so then do the same in your proofing workflow. Remember you are trying mimic what happens when you send a file to press...

Follow up: after a bit of reading/research I've found Tucanna PrintControl Pro. It's not cheap but does everything I was looking for: CTP curves, trending, custom colour bar creation and a lot more.

Erik, Generally they run to standard densities but will change the densities from time to time to hit a specific colour.. I don't measure any runs that are more than 4 DE from our target densities.

I really like PressSign, I will revisit it on Monday. I have uploaded the three bars that are used. We use the different bars based on how much space is on the sheet. I can't use the press colour bar at the moment. The press is density only and I can't access that data. All data collection is...

No Title I messed up uploading last time.

Yes there is variation and yes it is an inconsistent device but if you do a long term trend analysis, say 30-40 measurements over a few months you will see how the press moves. I've been doing this in excel and then plotting the values. I have attached a 90 trend for the dot gain for one press...

Anytime I see a Yellow cast it is usually because the device is seeing blue. i.e. Big optical brighteners / Fluorescence. Is the B value of the "problem media" in the -5 or higher/lower... Usually with media's with a -4 to a -8 I get a strong yellow cast when using the M0 filer. Try M1 to see if...

I am tasked with establishing a common colour appearance for 5 presses. As each press is added we start with a G7 press run. This is establishes the presses starting point. We have CTP curves for each press. I'm very familiar with the G7 process and NPDC's. I am fortunate that we only have 2...

I am not aware of those presenting on inkjet proofs, that's not to say they don't only that I haven't seen it.

Can you answer my specific questions: 1) Do (any) inkjet dot proofers show the same rosette structures that will be in the final presswork? 2) Do they show artifacts like subject moiré, screening moiré, ribboning, sawtoothing, image integrity (e.g. screened text) as they will appear in the...

Gordo, I would appreciate it if you would refrain from personal comments such as "flogging a dead horse", it really isn't advancing the discussion in a positive way. With that said, I have complied an image that shows a 50% dot on an inkjet and two press sheets. They are not all from the same...

The original poster ask for a comparison between Kodak and inkjet systems. I was very clear and opinionated about what I feel, if that was bashing then I guess that's bashing. I think the Kodak system is antiquated and a dinosaur and that's my opinion. I consider myself an independent colour...

My apologies for the slow reply. I was away over the weekend and unable to upload images with my phone. Here are some thought a customer should consider when looking at the two systems. 1. Comparing a printed sheet to the Kodak Approval? Kodak Approval is too sharp compared to any kind...

He is asking I am wondering if getting a higher end Proofing system such as the Kodak Approval would bring any further advantages to the DotProofing that couldn't be done via the more cost effective Epson printers. Keep in mind we do not print magazine quality. Our print tends to be mostly spot...

Agreed, the inkjets with a native resolution of 600 dpi on the Canon and 720 dpi on the Epson will never replicated the resolutions of the CTP (1500+), especially at LPI's of 150 or higher. I have seen results from 1 bit tiffs proofing for screen, newsprint and packaging proofing that are very...

DMP, run the printer until the ink is 100% used. You will get a message when the ink is out and replace then. No need to replace prior and nothing bad will happen

I would take a look at the Canon iPF printers. In a recent test I showed that the dot placement was tighter on the Canon compared to the Epson's. Canon iPF6450 vs Epson 7900 Comparison GMG has recently began recommending the Canon's for dot proofing over the Epson's.

Hello everyone, I am in the early stages of putting together a product summary / review of the software solutions available to the brand owners, a solution that allow them to measure, quantify, trend and control their brand colours. Looking for input on: What are the current solutions...

Epson's, when used often need to have the wiper blade assembly replaced or at least cleaned once a year. It is an easy replacement see this link for how to on the 7900. Not sure if it is the same on your printer. When this part gets dirty, the print heads will keep picking up gunk from the dirty...
