How Do They Work?
During printing, machines put different inks on packaging to make the images and text. The printer’s color blocks are printed at the same time in set areas. Then technicians or automated systems check them for:
- Color Fidelity: Making sure each ink color is right and matches the planned shade.
- Registration: Checking that colors line up properly with no overlap or gaps, which is crucial for clear images.
- Ink Density: Making sure the right amount of ink is used for each color to avoid smudging or fading.
By watching these things, printers can catch and fix errors fast, cut waste, and make sure the final product is good quality.
Why Are They Important?
Even though consumers might not notice them, they matter for these reasons:
- Brand Integrity: Consistent colors mean a brand’s packaging is easy to recognize and keeps consumers’ trust.
- Regulatory Compliance: Printing nutrition info, ingredients, etc., accurately is needed for the law and consumer safety.
- Production Efficiency: Catching printing problems early with these blocks stops big mistakes and saves time and resources.
