Editor's Note
Welcome to the sixth edition. What is the goal? Is just printing enough? Or is it appropriate that the colors are attractive and have high saturation? Definitely not. In many cases, we are not looking for printing with sharp and attractive colors, but the opposite. The colors that were created during the design should be accurate to the printing stage. And they can be part of the logo, the company’s brand book or the needs of the consumer market. The correct production of color and image quality depends on checking the solutions from the beginning and following the principles. These principles can be in the scientific part and in the executive part. For this reason, in this version, we examine the principles of halftoning, which is part of the production process, and then we discuss the wrong methods in choosing colors. One of the attractive parts of this version is the choice of color based on age, gender and scent, as well as checking the PDF/X rules and the production process in the LSS way, which can help you in professional design and correct printing.
Table Of Contents
1- Halftoning technology in prepress and printing
Halftoning is one of the most important parts in printing process. To improve your knowledge and information level we are going to review important topics in this filed. Lithography is the key part in the first step of halftoning. Through adjustment and correct selection of items such as screen angle, screen shape, screen resolution, halftoning can play an important role in production quality control. This section is suitable for all graphic designers and quality control managers who are active in prepress and Q.C. Although halftone is used in a repetitive process by printing houses but it is hoped that the information of this section will help to improve the quality of printing, color saturation and control the shadows of the image.
2- Wrong shortcuts to create color
One of the interests of graphic designers is the use of various features in graphic software, which is mostly defined for designing web pages. These features are available for designing a print file, but should be used cautiously. Software isn’t responsible for our mistakes. It thinks you are paying attention to all the procedure and will eventually correct the file. But sometimes the user uses the web design features for a print product and eventually sees a change in color or deterioration of quality and asks himself “why this happened ?!”. In this section, we want to talk about features such as Blending Mode and Opacity and its printing problems and see what the Flatten command solutions are in Adobe Illustrator to solve these problems.
3- Packaging engineering basic principles
When talking about production, many points come to mind: Printing, production cost, file optimization, compliance with standards, proper ink, perfect design and even marketing and sales… But is it enough to do all these steps correctly and carefully? Is only proper design and quality printing profitable for the company? Can hiring professionals for each of the mentioned departments guarantee the quality of production? These questions should be investigated. In this section, we are going to talk about Lean Production and talk about the items that are in 6Sigma. By examining these two issues, many tips for a good production are determined and you realize that only hiring the best designers or file adjustment in the best way can’t be efficient for production workshops and printing houses.
4- Three ways in color selection
For graphic designers and art directors color selection for an ideal design is always an attractive challenge. Sometimes our criteria for creating the correct color can be defined by matching with a calibrated monitor, choosing from a color book, or rules related to the color cycle or standard printing. In choosing the color, not only the creation of a beautiful work of art and accurate printing should be considered, but also the audience who intends to buy that product, as well as their age, should also be considered. Of course, the choice of color in the matter of packaging according to the market of the product, is much more important than the choice of color for the brochure. There are many points in the choice of color, but the point is that culture, population and even lifestyle can affect the choice of color by the artistic group.
5- Structure, benefits and methods of use: PDF/X
Since computers were used in the design process, the need for file standardization and integrity in storage was always felt. The variety of graphic files such as Tiff or JPG made users gain more experiences. But at the time of high-quality production, it is not possible to print in any format. So it is necessary to have a reference file in the printing house to sync with production needs. The programming language, features and coordination with printing devices have made the PDF format a standard for production but what is the history of this format?
