• Inland Provinces (e.g., Henan, Sichuan): $0.60–$0.75 per square foot – lowest price point, ideal for bulk orders with flexible timelines

Case Example: Total Cost of Ownership Analysis

Consider two hypothetical suppliers:

• Supplier A (Coastal): $1.05/sq.ft., 100,000 impression durability, 99.5% uptime compatibility
• Supplier B (Inland): $0.68/sq.ft., 85,000 impression durability, 94% uptime compatibility

At first glance, Supplier B appears more economical. However, factoring in replacement frequency, press downtime, and waste from misregistration reveals that Supplier A delivers a 12–18% lower total cost per million impressions over a 12-month period.

This underscores the importance of evaluating suppliers holistically—not just on price, but on longevity, compatibility, and service levels.

Frequently Asked Questions (FAQs)

What is CTP in offset printing?

Computer-to-Plate (CTP) technology digitally transfers image files directly to aluminum printing plates, eliminating the need for photographic film. This streamlines prepress workflows, reduces human error, improves dot accuracy, and shortens job setup times—making it the industry standard for modern offset printing.

What type of plate is used in offset printing?

Offset printing primarily uses aluminum-based photopolymer plates designed for CTP imaging. These plates are coated with light-sensitive polymers that react to laser exposure during the platemaking process. Aluminum substrates offer excellent dimensional stability and durability, supporting press runs exceeding 100,000 impressions.

What is the difference between CTP and CTcP plates?

CTP (Computer-to-Plate) systems use specialized plates exposed by laser diodes (thermal or violet). In contrast, CTcP (Computer-to-Conventional Plate) uses UV lamps to expose standard PS (pre-sensitized) plates through a digital mask. CTcP has lower startup costs and works with legacy plates, but CTP delivers faster processing, higher resolution, and better consistency.

Does offset printing require plates?

Yes, all offset printing processes require physical printing plates—one for each color (CMYK plus spot colors). These plates are mounted on the press cylinders and transfer ink via rubber blankets onto paper or other substrates. CTP technology ensures precise, repeatable plate creation essential for high-quality color reproduction.
