The main methods for controlling gray balance in printing include the gray balance curve, gray scale, gray balance test chart, and the G7 methodology. The following section compares the gray balance curve, the gray scale, the gray balance test chart,…

1. Standard Artwork Size for Catalogs
The design file size should be 291 × 426 mm (including 3 mm bleed on all sides).
Add a center guideline to divide the layout into two pages.
2. Standard Finished Size
The finished catalog size is 285 × 210 mm.

Because the cylinder-to-cylinder (rotary) method uses line contact, it can completely avoid the bubbling issues that may occur in flat-bed hot stamping, while also offering higher speed and better quality. However, since both the stamping plate and t…

Color separation plays a crucial role in ensuring accurate and high-quality printing output. Below are the common issues frequently encountered during the color-separation process and the challenges they may introduce:
1. Insufficient image resolutio…

1. Single-Page Printed Materials
When imposing single-page prints, leave a 6 mm bleed at the center joining area (vertical center line).
This means each page should have a 3 mm bleed on all four sides (requires two cutting passes).
Note:
If your prin…

In offset printing, multiple pages or multiple jobs are often imposed onto a large printing sheet to improve efficiency and reduce production costs. There are three common methods of double-sided imposition: Work & Turn, Work & Tumble, and Work & Bac…

Q: Many customers request converting spot colors to CMYK to reduce printing costs, yet still want the final print to match a specific Pantone color. This often creates challenges during prepress and the actual printing process. What are the best ways…

In print design, embossing and debossing (also known as relief or raised printing) are special techniques that can significantly enhance the tactile and visual quality of printed materials. However, many designers focus solely on the visual aspect of…

Problem Description:
Before baking, the printing plate appears clean with almost no stains. However, after baking, many small and irregular dirty spots appear. These spots are often invisible to the naked eye until the plate is mounted on the press a…

ncrease Precision During Linearization
When performing linearization, try setting a higher precision level. This helps achieve smoother gradients and reduces visible graininess in printed results.

1. Knockout
If blue text is placed on a yellow background, the area where the blue text appears must be left empty (knocked out) on the yellow plate. Likewise, the same area should be removed from the cyan/blue plate. Otherwise, the blue ink will be …

a. Be aware of highlight dropout.
b. Use complementary (opposite) colors carefully — it’s best to use only one complementary color if possible.
c. Ensure the total ink coverage does not exceed the paper’s ink absorption capacity.
Application of sp…

Trapping refers to a prepress technique used when two or more colors overlap in a design. During the plate-making process, slight adjustments are made to the size of one color area relative to another, based on the printing sequence. This helps ensur…

In offset printing, the four most common imposition methods are single-sided, sheet-wise (self-turning), work-and-turn, and work-and-tumble. Each method offers distinct advantages, and the appropriate choice depends on the product specifications, pre…

In the prepress stage, it is common to encounter images with distinctly different color blocks, where one color overlaps another. During printing, each color is printed separately, and due to mechanical inaccuracies, misregistration between color blo…

When preparing the layout for output, especially in traditional plate-making processes, two key factors should be considered:

Content Adjustment and Consolidation: The content should be adjusted or consolidated to fit within the layout, leaving mini…

1. Regular Cleaning
Perform cleaning regularly, refill with fresh developer solution, and carry out maintenance according to the manufacturer’s recommendations. All nozzles, tubes, brushes, and rollers should be cleaned frequently and replaced when …

Improving the durability of CTP plates is an important way to reduce production costs, minimize material waste, shorten production cycles, and increase overall efficiency. In modern offset printing, CTP (Computer to Plate) technology has completely r…

When book design is expressed through printing techniques, it must manifest itself in a specific way — through its display. A single point on a plane can generate a sense of spatial tension around it; similarly, when a book is placed on a bookstore …

In modern printing production, CTP (Computer-to-Plate) has replaced traditional film-based plate making, but blurred images on plates can still occur. Blurred images directly affect print quality and are mainly caused during the plate-making process.…
