Platemaker / Proofer

A platemaker prepares printing plates for different printing processes, ensuring the plates have the correct image, layout, and spacing for text and images.

This includes tasks like adjusting layouts using computer software, formatting images, and working with various types of printing plates.

Here's a more detailed look at what a platemaker does:

Tasks and Responsibilities:

• Image Preparation:

Platemakers ensure that the image to be printed is accurately represented on the plate, whether it's text, images, or a combination of both.

• Layout and Formatting:

They adjust the layout and formatting of text and images to ensure they fit on the plate correctly and appear as intended on the printed page.

• Plate Preparation:

This involves exposing sensitized metal sheets to special light through a photographic negative to create the image on the plate.

• Plate Processing:

Platemakers may operate machines that automatically process the plates, ensuring the image is properly etched or hardened.

• Quality Control:

They monitor the quality of the printing plates and make adjustments as needed to ensure the best possible print quality.

Platemakers may troubleshoot issues that arise during the plate-making process, such as misaligned images or imperfections in the plate.
