As many of you know that below pantone shaded inks are having lower fast properties:
Pantone warm red (Pigment Red 53:1)
Pantone Purple (Pigment Violet 1)
Pantone Violet (Pigment Violet 3)
Pantone Rhodamine Red (Pigment Red 81)
Pantone Blue 072 (Pigment Blue 1)
Pantone Reflex Blue (Pigment Blue 61)
These 6 shaded inks are not fast enough to light ( ranged from 3-4), UV varnish application, water based OPV application, lamination,etc.
So the ink producers are made the fast shades of these from resistant pigments of red 122 ( Rhodamine), Violet 53 ( violet) etc.
The hints for those who wants to mix them in their print shops, the required shades are cyan, orange 021, red 032, fast violet, fast rhodamine:
Pantone warm red (orange 021 + red 032)
Pantone Purple (fast violet + fast rhodamine)
Pantone Violet (fast violet should be supplied by ink manufacturer)
Pantone Rhodamine Red (fast rhodamine should be supplied by ink manufacturer)
Pantone Blue 072 (fast violet + process cyan)
Pantone Reflex Blue (fast violet + process cyan)
My recommendation for the print shops where these 6 shades are over processed, so they shoould not have the non-resistant versions in their warehouses since by any mistake they could be used in printing. Either should be asked from ink supplier or should ask to them only fast violet and fast rhodamine ( I assume orange 021, red 032 already in there and cyan already there) and then if they are good in mxing then mix them by themselves.
one problem I faced related to this: The printing house were pirnting a nice perfume box with a metallic gold, the the operator looked at the shade and said red is required and added at the amount of a nut into 1 kg pantone warm red and looked at the printed sheet,the shade was ok,and lamination was made, then the boxes sent to the customer and the boss has collected one box to keep in his room,then after 1 week the box had some cloudy colors on it, means the shade is not as it was, what happened all the boxes rejected from the customer.
The operator should use red 032 instead of warm red, and my suggestion is that all the users in printing shops should check the label of the ink to see the fating characteritics.
Do not forget that the chain is stronger as the weakest part's stregth, here even 1 grs of warm red added into the ink, the ink fast properties now have the properties of warm red, light is 3 and all the rest is non-resistant.
If by mistake anyone printed with non-resistant color, and has to make some application over it (not inline ofcourse), if the lightfastness is not important then one possible solution could be to print over it a thick layer of offset oil based opv then let it dry and make application ( by testing) why, since this OPV layer will prevent to reach either the ammonia from lamination glue or water based OPV and monomers of UV varnish to the non-resistant pigment, so no shade loses will be.
Some more hints for those who blends the inks as spots:
Pantone Rubine red has the same pigment as process magenta does ( Pigment Red 57:1)
Pantone yellow has the same pigment as process yellow has ( either pigment Y13 or Y174)
Pantone process blue has the ame pigment as process cyan ( Pigment B15:3)
so any of these shades are to be used to mix a oantone shade then you can use prcocess CMY whenthere is also tranparent white, since process colors are weaker then pantone colors. But you can estimate as below for conversion from pantone shades to process colors:
Depending on the color stregth of the process colors:
Process Yellow 60-80 % of pantone yellow
Process magenta 80-95 % of pantone rubine
Process cyan 80-95 % of pantone process blue
