Thanks for the note, BeauchamT Well, I am not sure what are the various filter. Are you referring UV filter or Polarized? If I measure density from Xrite 939, there is CMY and V. I am not sure what exactly what "V" stands for. may be visual? I want to measure density of various screens of...

Can you measure spot color density value? I know that I could measure density using Xrite 939 for CMYK, however when it comes to measuring spot color density such as Pantone 361 C (Green), how could I measure density using Xrite 939?

What is Maximum dot and Minimum dot is actually mean? For my own interest, I would like to know what maximum and minimum dot is really mean in print world. Especially rotogravure world. My assumtion for minimum dot is in what percentage of screen value can be achieveable when printed. For...

I am pretty sure you have your own way of matching colours with EFI rip which I have not experienced yet. But I do not believe EFI is only one who can match the spot colours. It might be your personal preference. As I pointed in my first writing, I had no problem with matching Spot colours with...

That is what my intention. Since Spot colours that we produce can obtain brighter white reference when ink is mixed. If you take a look at the Spot colour simulation in Rip software, such as ORIS & GMG (not sure of EFI), spot colour uses full printer gamut base on your paper reference profile...

We are creating Hard proof using ORIS+Epson7900. - not WT one and we are printing onto GRACoL Paper (pearl proof GRACoL certified) New ICC profile that we would like to match has darker white reference than GRACoL. - I know I have used bigger ink gamut (Paper reference) for Spot colour...

Here I am asking the question that I jumped into when I was setting up the RIP software with accureate spot colors. Here is my situation. We have ORIS 1.2.2 RIP + Certify proof equipped with EPson 7900 + on-board spectro. We also have Xrite 939 + iQC print for measurement and QC I have ICC...

comparison comparison Well, I believe GMG and other RIP software has its own Pantone Plus L*a*b* value, however these colors are modifiable since you can change the L*a*b* value. But again, what is the target of the Pantone Plus is the question not which reference is more accurate since...

Came back from DRUPA 2012, and one of things that pin pointed in my mind is Landa printing equipment. I am in Roto-Gravure world and since Landa Digital press states they can print on any substrate, my mind was blown. It seems to me the highlight of Graph Expo in 2010-2011 was Digital press...

I will be attending Drupa (2nd till 5th) and I will be more than happy to see some of people in Printplanet color gurus.

We also have ORIS RIP + EPSON 7900 for proofing solution which I have set tolerance method as ∆E. I hope I can get practical answers from people who decide to move towards ∆E cmc or ∆E2000 in order to compare proof, printed sample to visualize the color similar to human eye observation...

Well, I think Pantone should control the swatch book, and colour chip set more carefully and tightly. I have experienced ordering swatch book and chip set having ∆E over 5-6.Over three months ago, I compared upgraded pantone library (from Pantone website) vs Swatch book (swatches and chip set)...

Can anyone can tell me difference between these three, (∆E, ∆E cmc, ∆E 2000) usage in print QC industry? By gathering information in internet, it seems like ∆E is used in wide range, however the ∆ value seems work similar concept as absolute colormetric way, in other word, ∆E value...

I have another question then. If Pantone need to be applied on substrate before finding Lab value, then should same pantone color will have different lab value depends on different substrate? Even you are using different substrate, shouldn't they need to have same lab value range? (Or if Pantone...

Thanks Gordo for the answer. I am not sure how gravure or flexo ink is mixed, but to match the pantone color for using transparent substrate, what would be the pantone standard? Does Pantone has special mix receipt for the Flexo and Gravure? I have to ask this question then, what would be the...
