Strategies for regulating the structure of PDF pages and improving the efficiency of layout

1. Standardize the design of PDF pages

Formulate standard operation manuals on PDF page design, train employees, communicate with customers, and hope that employees and customers can design PDF pages in accordance with standardized requirements. There are:

â‘ In Indesign and Illustrator software, create a page structure box such as MediaBox, TrimBox and BleedBox for PDF pages.

â‘¡Set the four-sided bleeding for the PDF page when setting the page properties, and unify the bleeding size.

2. Use Acrobat and Pitstop software to regulate PDF page processing

For non-standard PDF pages, use Acrobat and Pitstop software to process them before the big version, mainly:

â‘  For pages with three-sided bleeding, the pages are treated as four-sided bleeding by increasing the page size in Acrobat.

â‘¡ For the spread file, the page should be split into a single page file before the layout work.

â‘¢In Pitstop, add media frame (MediaBox), cut box (TrimBox), bleeding box (BleedBox) and other page structure boxes to the page. In this way, the software can automatically recognize the page structure frame when positioning the layout, and perform automatic positioning.

3. Standardize the use of layout software

For different PDF pages, a unified PDF page positioning template is established in the layout software to form an operation specification, so that different operators have the same operation method.

The fourth step is to fix the separator support bar on the rainbow printing device with the help of the round pin alignment system. In this way, even if the customer wants to use multiple support bars for repetitive work, there is no problem. It saves time because no adjustment is required. The fifth step, between the divider and the divider, and between the divider and the squeegee and ink fountain roller must be well sealed. It is worth mentioning that we use a special silicon sealing material. Therefore, there is no adjustment screw on the divider-no tools are needed, just insert it easily-this saves a lot of time and does not require other connection or adjustment work. In the sixth step, it is necessary to reduce the movement range of the ink-feeding roller. This task must be completed on the transmission side of the printing press--precision, stepless, reproducible, and fast. If necessary, the ink supply unit separation and short-path ink supply modes may also be used.

If waterless offset printing or dry offset printing is not required, the bridge roller of the dampening system must be replaced with a non-sloshing type. After the ink key setting is completed, the printing press is ready. The operator only needs 5-10 minutes in total to prepare the rainbow printing system in place. Rainbow printing device is designed and developed according to the special needs of customers. When producing long-form jobs, such as over 10,000 prints, we recommend the use of special ink fountain rollers with circumferential grooves to avoid ink color migration.

Rainbow printing technology is now widely used in Heidelberg Speedmaster SM52, SM74, XL75, CD102 and SM102 series products. In 2007, the world's largest banknote printing company-China Banknote Printing and Minting Corporation-installed 12 Heidelberg Speedmaster CD102 printing machines at its six branches on the mainland, all of which were equipped with a rainbow printing system . In Europe and the United States, manufacturers specializing in anti-counterfeiting printing are also using Heidelberg rainbow printing technology. In July 2010, the 150th Heidelberg printing unit equipped with a rainbow device was installed in a Russian anti-counterfeiting printing company with the Speedmaster SM102 six-color UV offset press. A Dutch printing house also recently started using their first Speedmaster XL105 offset press equipped with a rainbow printing system.
