Paper Stocks

• Uncoated: Absorbent, provides a matte finish.
• Coated: Has a smooth surface, provides a glossy finish.
• Specialty: Includes textured, metallic, and translucent papers.

A Digital Proofing and Platemaker is responsible for preparing and maintaining printing plates used in offset printing processes. They ensure that the plates accurately reproduce the desired image or text onto the printing surface, producing high-quality printed materials. Key responsibilities include:

1. Digital Proofing

Proofread and review digital proofs to ensure they meet the customer’s specifications and are free from errors, such as color inaccuracies or missing elements.

2. Platemaking

Create and process printing plates using computer-to-plate (CTP) technology, ensuring that the plates adhere to the print job requirements and industry standards.

3. Plate Maintenance

Maintain, clean, and inspect printing plates throughout the production process to ensure optimal performance and longevity.

4. Quality Control

Monitor and evaluate the quality of printed materials produced from the plates created, identifying and correcting any issues that arise.
