Standing in the printing industry point of view, whether the choice of printing desk calendar and wall calendar in which one, any time can ensure the printing quality consistent? If you want to print quality, we must follow certain standards. Factors affecting printing quality effect has the following six points:
One, the quality of the printing ink
Ink affects the quality of printing is very big. Different liquidity each of the ink, the ink color is also different, printing factory in each batch of purchase should also have the corresponding measurement and statistics, in order to ensure the stability of the quality of different batches.
Two, the quality of the paper
Only in the procurement time for each batch of paper test, while the test data to the paper business, it also can supervise the power paper quality is getting better, ensure that the paper's qualified.
Three, color conversion platform
If the customer to our RGB file, convert CMYK to us by what means? If the conversion is used by each printed standard is not the same, then the converted CMYK file color will be different. Secondly, even if the same file, through different printing digital printing, offset printing, gravure printing, printing out of the color will also vary.
Four, file conversion
In addition to the total network not the same may affect the final printing color effects, and network technology, the network of different type of its different dot gain rate is different. For example, if this CTP device is broken, you go with the other CTP to the publication, the difference between the final printing color may have a certain amount of.
Five, the different devices
We also ignore the factors in the printing process: equipment of dot gain rate.
Each printing equipment, dot gain rate is not the same. That is to say, even give you the same version, substrate and supplies the same, in different presses are not able to get similar printing. So the relevant operators understand the dot gain rate of this concept is very important. CTP not only can do a variety of data acquisition, can also be used for dot compensation.
Six, the publication process
Because the plate manufacturer technical, plus net and dot gain different definitions, the plate dot exposure rate and different plate equipment will affect printing quality. If the publication process does not have a uniform standard, difficult to do each batch printing are the same.
