Even with modern printing using CTP (Computer-to-Plate) technology, blurred images on plates can still occur. Blurry plates directly affect print quality and usually happen during the plate-making process. Here’s a detailed breakdown of the common causes:
Achieving flawless printing takes more than just running the press — it’s about consistent monitoring, quick adjustments, and proper maintenance. Here’s a professional checklist to help you deliver top-quality results every time.
Choosing the right paper is essential for achieving the best results in book printing:
Inner Pages:
Offset paper (also known as woodfree paper) is ideal for clear, non-reflective printing. Common thicknesses include:
60gsm, 70gsm, 80gsm, 100gsm, 120gsm.
Covers:
We recommend 250gsm or 300gsm coated paper (art paper or coated artboard) for a sturdy, professional appearance.
The binding method depends on the spine thickness:
Spine < 3mm: Saddle Stitch Binding
Spine > 3mm: Perfect Binding
Other available options include:
Wire binding, Comb binding, Strip stapled, Ring binding, and Hardcover binding.
We support a wide range of customizations to bring your vision to life:
Sizes: A4 (210×297mm), A5 (148×210mm), B5 (176×250mm), or custom dimensions
Printing: Black & white, full color (CMYK), or custom color matching
Special Finishes: Lamination, UV printing, hot stamping, embossing, custom shapes, and more

Design and layout are the foundation of quality printing. This stage involves arranging your content, refining every detail, and finalizing the document before printing can begin.

Before mass production, we create a digital proof to identify and correct potential issues. Minor color variations from final prints are normal due to proofing methods. Once the proof is approved, we schedule full production.
This stage includes:
Typesetting check
Hard blueline proofreading
CTP (Computer-to-Plate) plate making
Paper procurement is also arranged at this time.
Books are printed using high-performance machines, followed by precise binding. Each method has a specific workflow:
Saddle Stitching: Folding → Binding → Quality Control → Packing
Perfect Binding: Folding → Gathering → Glue Binding → Trimming → QC → Packing
Sewn Binding: Folding → Gathering → Sewing → Glue Binding → Trimming → QC → Packing
Hardcover Binding: Folding → Sewing → Binding → Trimming → Greyboard Lamination → Bookblock Assembly → QC → Packing
In traditional multi-color letterpress and lithographic printing machines, the inking system consists of a series of rollers, including the ink fountain roller, ink transfer roller, ink distribution roller, ink oscillating roller, and ink form roller, among others, totaling up to twenty or more rollers. While this system generally meets the requirements for ink transfer, it struggles to maintain a constant ink supply. In contrast, flexographic printing machines utilize a short inking system, where the anilox roller provides a consistent and uniform ink supply through its engraved cells. The anilox roller plays a pivotal role in flexographic printing, and understanding its proper use and maintenance is crucial for avoiding operational errors, improving product quality, and enhancing production efficiency.
It is well known that materials used in the packaging and printing industry, such as paper, plastic, ink, adhesives, and guide rollers (some of which are anodized to form alumina), are insulators. The processes of printing, laminating, rewinding, and slitting are high-speed operations that involve friction, contact, and separation—essentially "surface" engineering. The generation of static electricity in packaging and printing plants is mainly related to the chemical composition, molecular structure, mechanical properties, smoothness, and electrical properties of the insulating materials, as well as environmental factors like temperature, humidity, and external mechanical actions such as contact pressure and the speed of frictional separation. The type of film, contact method, contact time, contact area, and separation speed all influence the time of static discharge and the voltage produced.
Paper is the main substrate for printing, and the quality of paper directly affects the quality of printed materials. There are significant differences in the glossiness, surface strength, whiteness, absorbency, smoothness, and dimensional stability of different paper types. Even under the same printing conditions, the same ink will produce different color effects on different papers. The surface characteristics of the paper directly reflect the tonal levels and colors of the image, determining the plate-making tonal and color standards. Therefore, in practice, it is essential to fully understand the printing characteristics of paper and determine the printing parameters accordingly to enhance the quality of printed products.
