Five Key Points of Prepress Layout Impact on Silkscreen Printing Quality
Silkscreen printing involves multiple prepress steps. To produce a high-quality silkscreen product, every step must be executed without error. Even a minor mistake in any step can prevent achieving the desired print quality. The prepress process can be broken down into scanning, layout design, film output, proofing, and exposure, with the actual silkscreen printing coming last.
Layout design is a crucial step that combines text and images, and adopting standardized and structured layout practices is essential to ensure and enhance print quality. The main factors impacting quality in this process are as follows:
1. Inconsistent placement of text, images, color blocks, and gradients can make the layout appear overcrowded or sparse, affecting the overall aesthetic.
2. Visual differences can occur due to disparities between on-screen appearance and the resolution and color modes used in actual silkscreen printing, resulting in a printed product that may not match the intended look.
3. Using multi-color registration on small fonts or fine lines may lead to registration misalignment and ghosting effects.
4. Directly using RGB format in layout design can turn images to grayscale.
5. Stretching or compressing images during layout causes image quality degradation and slows output. Enlarging images, in particular, significantly affects visual quality. To avoid these issues, layout design must strictly follow standard guidelines: images should be in CMYK format, and resizing should be done in Photoshop instead of distorting images in the layout. Text blocks, images, and color blocks should maintain uniform spacing; font kerning should generally remain unchanged for a visually pleasing result.
By addressing these key points in the prepress stage, a silkscreen print shop can lay a solid foundation for achieving high-quality silkscreen products.
