Hi Magnus, It sounds interesting with combination FM-C M Y and AM-K. Beside the better appearance, how do you think about the stability of color, especially gray tone (ex: CMYK = 50 40 40 15)

Hi RayC, Thank you for your interesting feedback! But I got the constant value when I measured the client's sample, and with the same measuring condition I get the variable value when I measure out sample. So I guess the key point is type or kind of matt lamination film, but I am very lack of...

Hi Steve, The measuring value is constant if I use M0 (did not try M1 - but I guess it same as M0). The caution here, in my opinion, it is M3 (polarized filter) and matt film. Our client requests us to use M3 (pol) D50/10. When rotate the finished product, it looks same. Not sure about the...

Hello Experts, I am not sure this post suitable here or in color management area, please move it to correct area if needs! I have to measure a color sample which is printed a spot color - standard L*a*b = (48.6, -0.50, -2.16) after matt-film lamination. Measuring condition is D50/10 and M3...

the Sunlight will be changed from morning to afternoon, from cloudy day to sunshine day,... so your standard light has been changed... it is not good for color checks, is it? Even we use standard light (D50) for checking color, our clients could compare the printed color everywhere they want...

how could we convince the client that the color is fine? It depends on their opinion, their feeling and their mood; there is always different point even nonsense if they intend to look for... "our client is always correct"

@gordo It might be not related to this topic, and I have question about process control, especially in prepress when I make plates with very high resolution (more than 300 lpi with AM, or 10 micron with FM). What do you think about the acceptable tolerance for plate dot area in 1%, 25%, 50% and...

WOW, it is good to read this response!

Thank you, I will

In my opinion, this ink will absorb UV light and emit some visible light. So I recommend you to use spectrophotometer with light source with UV light (like xrite eXact - M1). See picture for your infomation! Regards, Delta E

Hi All, I have been using Pistop 2012 for years, which is very easy with an action "Devicelink profile" in order to reduce TAC of printing file. I want to update and just install newer version 2018, use same action and same devicelink profile as in Pistop 2012. When I click on "Run" button of...

:cool::cool::cool: It is nightmare of printer! ha ha ha

Erik Nikkanen Thank you for great input!

cementary Thank you! The condition of inking and dampening rollers is very important to uniformity! Last week, when we made a G7 colorspace, I had the density deviation from front to tail: - Black: +/- 0.05 - Cyan: +/- 0.04 - Magenta: +/- 0.04 - Yellow: +/- 0.03 It was fine for us to get a...

Hello everybody, I have a question about the solid ink density in circumferential direction, the uniformity of density in sheetfed offset machine (ex: Heidelberg CD102, Rapida 106, Man Roland 700, Komori,...) How can I improve the uniformity of ink density on the circumferential direction? I...

prepress labels You are so bad! :mad::mad::mad::mad::mad:

Please tell me the CMYK composition of your "Dark Blue and Purple"!

Hi there, If I right understood, it is hard for you to match the offset printout with the proofing (from Epson which is simulated in GraCol 2013). Here is my idea for you: Your custom profile (your machine, curves, SID, Lab of CMYKRGB,...) now is not matched with Gracol 2013. It causes your...

In my point of view, you need: - Ensure that the offset machine is in good condition (no doubling, no slurring, no color variation, no streak marks), enough printing pressure, no scumming or smearing. The ink density should be in tolerance through horizontal and vertical direction.... - OBA as...
