Rather, these embodiments are provided so that this disclosure of economical printing methods, apparatuses, terminals and computer-readable storage media based on the GRACOL2013 standard is more thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the economical printing method, apparatus, terminal and computer-readable storage medium based on the GRACOL2013 standard is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Example 1
Referring to fig. 1, the embodiment provides an economical printing method based on the gradol 2013 standard, which includes steps a to D:
step A: and establishing a basic characteristic file according to the actual printing production conditions. The actual printing production conditions refer to hardware conditions such as printing paper, printing ink, and printing equipment actually used by a printing plant to produce products based on the GRACOL2013 standard.
Referring to FIG. 2, step A includes steps A1-2:
step A1: actual printing paper characteristics, actual printing ink characteristics, and actual printing device characteristics corresponding to GRCOL standard prescribed parameters are acquired. The characteristics of the actual printing paper, the characteristics of the actual printing ink, and the characteristics of the actual printing device are numerous and complicated, and only the characteristic parameters corresponding to the predetermined parameters of the GRCOL standard may be acquired. Wherein, corresponding means that the parameter types are consistent.
Step A2: and establishing the basic characteristic file according to the actual printing paper characteristic, the actual printing ink characteristic and the actual printing equipment characteristic.
Exemplarily, the actual printing paper characteristic includes at least a Lab value of the actual printing paper. The Lab value includes three elements, i.e., a luminance (L) and two color elements (a, b), a representing a range from magenta to green, and b representing a range from yellow to blue.
Exemplarily, the actual printing paper is single copper paper. The Lab value directly reflects the surface quality difference between the single copper paper and the double copper paper, and corresponding switching adjustment is needed according to the Lab value, so that the defect of single copper paper printing is overcome, and the printing quality close to that of the double copper paper based on GRACOL2013 is obtained.
And B: and establishing a conversion model according to the basic characteristic file and the GRACOL2013 characteristic file.
It will be appreciated that the conversion model forms the conversion equation from the base feature file to GRACOL 2013. Wherein, the basic characteristic file is consistent with the GRACOL2013 characteristic file in parameter type. Based on the surface quality difference between single-copper paper and double-copper paper, the paper characteristics (such as Lab value), printing ink and printing equipment parameters need to be adjusted accordingly. Therefore, the image parameters of the coming sample image file are adjusted and converted according to the basic characteristic file comprising the characteristics of the actual printing paper, the characteristics of the actual printing ink and the characteristics of the actual printing equipment, so that the coming sample image file is converted into a printing file which meets the GRACOL2013 printing requirements based on the single copper paper printing conditions.
Referring to FIG. 3, step B includes steps B1-4:
step B1: and establishing a paper conversion sub-model according to the actual printing paper characteristics and the GRACOL2013 standard paper characteristics. Exemplarily, a paper conversion submodel is established based on the characteristics of the single copper paper and the double copper paper, and a Lab value conversion equation between the two is formed.
Step B2: and establishing an ink conversion sub-model according to the actual printing ink characteristics and the GRACOL2013 printing ink characteristics. Exemplarily, the printing inks used by the single copper paper and the double copper paper have different Lab values, densities, color differences, viscosities, etc. based on the difference in surface quality between the two papers. The ink conversion submodel forms the conversion equation between the printing inks required for two types of paper.
Step B3: and establishing a device conversion sub-model according to the actual printing device characteristics and the GRACOL2013 printing device characteristics. Exemplarily, the parameter settings of the printing equipment used by the single copper paper and the double copper paper differ based on the difference in surface quality between the two. The equipment conversion submodel is a conversion equation between equipment parameter settings required for forming two types of paper.
Step B4: and establishing the conversion model according to the paper conversion sub-model, the ink conversion sub-model and the equipment conversion sub-model. The conversion model comprehensively considers the paper difference, the printing ink difference and the printing equipment characteristic difference to form a comprehensive conversion equation (set) which is finally reflected in the conversion relation of the picture parameters.
And C: and converting the incoming sample drawing file according to the conversion model to obtain a conversion drawing file. According to the conversion model, the picture parameter conversion can be directly carried out on the incoming sample picture file. The converted image file is synthesized with the paper difference, the printing ink difference and the printing equipment characteristic difference, can be directly printed based on the actual printing paper, the actual printing ink and the actual printing equipment, and has the operation convenience and the accuracy of one-time conversion.
Step D: and acquiring Lab values of a test sample and a standard sample, and judging whether the color difference between the test sample and the standard sample is within a tolerance range, wherein the test sample is a test printing product of the conversion drawing file, and the standard sample is a test printing product of the coming sample drawing file based on GRACOL2013 standard (namely double copper paper is adopted).
The tolerance range is a permissible deviation interval of the printing quality completely based on GRACOL2013 standard (namely, double copper paper is adopted), and in the interval, the printing quality requirement of the GRACOL2013 standard is met. It is mainly manifested as color difference, which generally includes lightness difference, chroma difference and total color difference. If the color difference is within the tolerance range, the test sample is shown to meet the printing quality requirement of GRACOL2013 standard. Otherwise, the steps A to C should be executed again until the requirements are met. Practice shows that the quality of a test sample printed on single copper paper by using the method meets the printing quality requirement of GRACOL2013 standard.
Referring to FIG. 4, step D includes steps D1-3:
step D1: and acquiring Lab values of the test sample and the standard sample.
Step D2: and calculating the lightness difference, the chroma difference and the total color difference of the test printing sample and the standard sample. In the Lab color mode, the lightness difference is Δ L, the chroma differences are Δ a and Δ b, and the total color difference is (Δ L)2+(Δa)2+(Δb)2。
Step D3: and comparing and judging whether the lightness difference, the chroma difference and the total color difference are within the color difference allowable range. If the judgment results are yes, the printing quality meets the requirements, and the method can be used for mass production.
