Printing common sense-how to read Pantone color card
1. What is the difference and connection between PANTONE 256 C and PANTONE 256 U, PANTONE 256 M or PANTONE 256 matte?
A: They all said that the same spot color ink, PANTONE 256, is the only one, namely PANTONE 256. Difference: The ending number is "C": PANTONE 256 C indicates the effect of printing PANTONE 256 on glossy coated paper, and its corresponding standard should be the spot color guide color card of glossy coated paper (coated); and so on PANTONE 256 U indicates the effect of printing PANTONE 256 on offset paper or specialty paper. The corresponding standard should be the spot color guide color card of uncoated paper; PANTONE 256 M or PANTONE 256 matte are the same, which means that PANTONE 256 is printed on matt coated paper, and its corresponding standard should be the matte special color guide color card.
2. What is the difference between printing PANTONE spot color with four-color ink, CMYK, and printing directly with PANTONE standard spot color ink?
Answer: CMYK is printed by dot printing with up to four types of ink; spot color ink is printed by one ink in flat coating (solid color printing, dot is 100%). For the above reasons, the former is obviously gray and dull; the latter is bright and bright. Because spot color printing is a solid color printing and is specified as a true spot color, CMYK spot colors can only be called: simulated spot colors, and the same spot color is clearly visible: for example, PANTONE 256 C must have a certain difference in hue of. Therefore, their standards are two standards. Please refer to "Pantone Solid To Process Guide-Coated". If you pass the CNYK printing spot color, please refer to the analog version as the standard.
3. What is the coordination relationship of "special color ink" in the whole process of design and printing?
Answer: This question is mainly for printing designers. Usually designers only consider whether the design itself is perfect, and ignore whether the printing process can achieve the perfection of your work. There is little or no communication with the printing house during the design process, making your work a lot less colorful. Similarly, there may be less consideration of spot color inks, or no consideration at all. To give an example to explain such problems, you can understand the meaning of it in one case. For example: Designer A has designed a poster poster, using PANTONE spot color: PANTONE356, part of which is standard spot color printing, that is, solid (100% dot) printing, and the other part requires screen printing, which is 90% dot. They are all printed with PANTONE356. If the spot color part of the field meets the standard required by the PANTONE spot color guide during the printing process, the screen hanging part will be "blended". Conversely, if the amount of ink is reduced, the part of the screen hanging will be appropriate, and the spot color solid part will be lighter. To PANTONE356's spot color guide standard.
Therefore, designers must consider or should know the blind spots existing in spot color ink solid printing and screen printing in the design process, and avoid the blind spots to design the net hanging value. Refer to: Pantone Timing-Coated / Uncoated Guide, the value of the net should be consistent with the PANTONE net value standard (.pdf). Or in your experience, those numerical nets can be linked to those that cannot. You may ask whether the performance of the printing machine is not good, or the operator's technology is not good, or the operation method is not correct. This requires communication with the printing plant in advance to understand the highest performance of the printing machine, the level of the operator, etc. Wait. One principle: let your work be realized perfectly by printing, try to avoid the process that printing cannot achieve, so as to realize your creativity perfectly. The above examples are not necessarily particularly appropriate, but just to illustrate that designers should consider the use of spot color inks and communication with printers.
4. What is the difference and connection between modern ink color matching technology and the international standard-PANTONE standard?
Answer: the same point: the two are both computer color matching; the difference: modern ink color matching technology is the ink formula of the known color sample; the PANTONE standard color matching is the color formula of the known ink formula. Q: If using modern ink color matching technology to find the PANTONE standard formula is more accurate than the PANTONE standard color matching method, the answer is: why already have a PANTONE standard formula and why not ask for a formula, it is definitely not as accurate as the original formula. Another difference: Modern ink color matching technology can match any spot color, PANTONE standard color matching is limited to PANTONE standard spot color. It is not recommended to use modern color matching technology to match PANTONE spot colors.
