Although Hong Kong is still in its infancy in adopting digital manuscripts, some printing companies have only printed digitally written manuscripts that are satisfactory to customers. This proves that digital manuscripts are not as difficult to grasp as rumors. This article begins with the analysis of the elements of the drafting, summarizes the advantages and limitations of digital writing, so that readers have a reference in the application.
The relation between scripting and printing
From the production point of view, color printing is a process based on the principle of dot color rendering, and production requires strict precision and stable repeatability. However, there are many factors that affect printing color, such as the characteristics of paper, ink thickness, printing pressure, air humidity, and even the quality of the plate. Some factors will influence each other, and the increase or decrease of each factor will cause other factors to change, which will affect the quality of printed color. Therefore, there is a need to estimate the combined effects of various factors on the prints before production so as to make adjustments. The drafting is a production simulation before actual printing.
In general, the manuscript provides the following three functions: First, it is used to check the effect of color separation and plate-making to determine whether the color of the picture is processed correctly and provide a basis for revision. Second, it is used to check the technical requirements of film registration and dot gain, as a reference for actual printing. Third, as a communication tool, the customer should sign and confirm before printing, and it is the standard for receiving goods in the future.
Ink-printing color quality
Due to the importance of the drafting process in the printing process, a strict printing factory is required. In addition to the establishment of data to control production, the conditions for drafting will also be adjusted to very close to actual printing conditions. For example, the paper used for each manuscript is the same batch of paper used for actual printing. The wet ink is used for wet printing and the press pressure of the manuscript is also adjusted to the pressure used for actual printing. In this arrangement, the printing properties of the paper and the dot enlargement are reflected. The reference role of the produced draft in actual printing is of course of very high value.
However, it is necessary to pay a certain cost to print such high-quality prints. In addition to investing in additional space for stacking paper, investing in additional equipment to control humidity, there are also technical specifications for the process of writing the draft itself. One of the most important ones is the density of the groundwork in the drafting. It is required to be the same every time.
The copywriting service on the market generally uses a monochrome flat sheeting machine. The supply of ink and pressure adjustment is decided by the master according to the situation, and the objective of the writing is pleasing to the eye. However, this practice often sacrifices the stability of the color of the manuscript, and less takes into account the printing requirements, resulting in the same set of film, twice the draft, they will get two different results, but also make the actual printing and writing color There are often considerable differences. Between the printing house and the buyer, disputes often occur.
Because of the way manuscripts are manuscripted, there are serious shortcomings in color instability. Therefore, in the 1980s, foreign printers gave up ink printing and replaced them with more stable chemical writing. The most commonly used ones are ColorArt. , Cromelin, MatchPrint, etc. However, chemical drafting only produces one draft at a time, and there is no stacking draft. This is unwelcome for the masters of monochrome and two-color machines. It is therefore unwelcome and the materials used are not welcome. More expensive, chemical drafting has never been popularized in Hong Kong, and the formation of master printers in Hong Kong generally lacks experience in handling non-ink drafting.
