I would like to use Colorplan's Tabriz Blue paper for the pocket fold (from Paper Presentations) that will hold my invitations. Paper Presentations calls Tabriz Blue "Ocean" (and confirmed that this is the same paper). In order to match the ink color in my invitations to the Ocean pocket fold, I need the CMYK and the Pantone numbers. These are available on the website of other companies but I am not sure how reliable this is (e.g., Paper Presentations' CMYK numbers assigned to Ocean turned out to be completely wrong and are now being revised, according to the company. One invitation website, Cards and Pockets, says that the CMYK for Tabriz Blue is 83-16-9-5. Also another website, Paperworks, says the closest Pantone color match is 7460. But I would like to know what Colorplan says is the correct CMYK and Pantone number for YOUR paper please so that I can pass THIS info to my invitation maker. Thank you!

Hi Karen, Thanks for your question. The closest PMS match to the Tabriz Blue is the Pantone 639 U. There have been some technical issues with the colorplanpapers.com site, which are being fixed over the next few weeks. I believe a Pantone reference chart is something the mill will implement during this time. Please let us know if you have any further questions.

Thank you! I will assume unless you tell me otherwise that this is the definitive Pantone number and I can ignore other numbers that some of the invitation companies are using, like Paperworks' 7460. Also, you did not tell me the CYMK of 639 U, which I need to give to the invitation people. When I looked at the various online conversion charts, I kept getting different numbers, so I really want to know which CYMK formula I should be using

Will you please confirm that once I have the Pantone and CYMK from you, there is absolutely no need for me to pay extra for the company printing my invitations to "color-match" the ink to the paper. This will have already been done for them, right?

Thank you again!

Hi Karen, Pantone 639U is 85c, 23m, 6y, 0k

Please note that the Pantone color 639U is the closest match found to the actual paper color. As the paper-making process is unique for every production there will always be very slight variations between batches. In most cases these differences are very subtle and not noticeable, but it's important to make note of this. This is one of the reasons why the mill does not publish Pantone references.

That information is so helpful! Thank you so much. May I trouble you please to send me one more piece of the puzzle that the person doing my invitation envelope addressing needs to know: the RGB. Do you have that info readily available? Would really appreciate it.

When we plugged in the numbers we got 0r, 151g, 204b.

Now I'm totally confused: When I use this converter, using the RGB of 0, 151, 204, I get this darker blue (seems more correct, I think?), with a CMYK of 100, 26, 0, 20:

https://kuler.adobe.com/create/color-wheel/?base=0&rule=Analogous&selected=0&name=My%20Kuler%20Theme&mode=cmyk&rgbvalues=0,0.592156862745098,0.8,0.6000000000000001,0.5339421252369448,0,0,0.7100000000000001,0.056441453940117306,0.297995922460191,0.03549999999999988,0.7100000000000001,0.8,0.040000000000000036,0.040000000000000036&swatchOrder=0,1,2,3,4

When I instead plug in your CMYK of 85, 23, 6, 0, I get an RGB of 38, 196, 240 (and a lighter blue):

https://kuler.adobe.com/create/color-wheel/?base=0&rule=Analogous&selected=0&name=My%20Kuler%20Theme&mode=cmyk&rgbvalues=0.15000000000000002,0.77,0.94,0.74,0.6609008109934514,0.11808510638297877,0.13563829787234047,0.85,0.158150592131707,0.40854301991798925,0.17813829787234042,0.85,0.94,0.1970000000000001,0.2599816517746334&swatchOrder=0,1,2,3,4

Please advise which is correct? And why they are different?

Karen, the most accurate measurement will be the Pantone color as we visually eyeballed the Pantone swatch against the actual paper. We then used Photoshop to plug in the Pantone color, which generated the CMYK and RGB values. Unless you are using a calibrated monitor you won't be able to determine visually on your computer screen an exact match. Most designers use Pantone as a reference, so if you supply this to him/her you should be good to go.
