Hello,
When opening the same pantone solid coated colours from 2 different versions of the books they look visually quite different. For example a customer has sent me artwork that has 7546C in it from the "previous version" book. If I choose that same colour from the Pantone+ Solid Coated-V4 book it looks a lot darker. The darker version visually looks coser to the actual PMS book i have here and that would also match the mixing system version of the actual ink. But if a customer is choosing a colour based on what they see on the screen and dont have a physical colour book this could cause some issues.
Seems very odd that the colour wouldn't look the same across different versionsof the books.
Are you comparing actual printed color books or comparing color books to the screen?
The Pantone 7546C color and 7546 in the Pantone + Solid Coated-V4 are different computer palette.
The reality is that the printer will use the formula printed on the swatch from the book so you would need to compare those mixing formulas from the two books to know if the colors are the same.
What you may try is making sure that CorelDRAW is set to use LAB for spot color conversions and convert the 7546C color and the Pantone +Solid Coated-V4 version of 7546 to CMYK and see if they convert to the same CMYK.
If it does not convert to the same CMYK colors I would suspect that they're different colors. If they convert to the same CMYK numbers I would assume that they are the same color and that the difference in the palettes is just a display change.
Just remember that there is no difference between C and U pallets for the actual printer they use the same ink to print onncoated as they do for uncoated paper.
The C and U pallets are only for the computer display simulation and will produce different CMYK conversions in the computer.
Hello, I'm comparing what I am visually seeing on the screen in corel. I understand that older physical books can fade a bit so comparing an older book to a new one can show some variations.
I thought I'd attached a corel file to my original post where you could see the 2 differing colours. I just drew a box and filled with 7546C from the previous version book then another from the V4 book and you can see quite a difference.
If you have CorelDRAW set to use LAB for spot colors for conversion to CMYK do the two samples convert to the same CMYK numbers?
when i go into fill colour and change over to the colour viewer tab the CMYK breakdowns are different. This makes no sense to me. Wouldnt the same PMS colour be the same regardless of which solid coated book it's from? Don't the newer books just have extra colours but existing colours stay the same? Theyre both 7546C from the solid coated book. Just one is from the V4 book.
Sorry i don't understand what you mean about the LAB spot colours?
When it comes to printing it's not an issue beause i print out a formula from a program and the i can compare the printed colour on a shirt to the phycial solid coated book.
the potential issue is if a customer sends us artwork and they've got colours from the previous version book and they may not have a physical book so can only go by what they are seeing on their computer screens. with this 7546C the artwork version looked a lot lighter being from the previous version book. When i brought up the V4 version it was much darker. I spoke to the customer and ended up printing 7545C as the V4 version looked like a closer match to the 7546C from the previous book version when viewed on the screen.

I believe there can be a small difference on screen, depending on which version these Pantone palettes are.Maybe because they have found that the old version doesn't look correct when shown on screen, or when printed on a CMYK printer.The color mix (I mean when physically mixing Pantone inks for offset printing for example) should still be the same, I guess.
