Dot gain (also called tone value increase, or TVI) is the phenomenon where halftone dots printed on the substrate are larger than their intended size on the printing plate. In flexography, dot gain is

Color variation from the beginning to the end of a single flexo roll is one of the most frequent sources of customer complaints. Unlike a sudden defect, this type of shift is rarely caused by a single

Cracked photopolymer plates are one of the most frustrating—and costly—problems on a flexo press. A single cracked plate doesn't just ruin print

Investing in new label‑making equipment forces every label converter to face one core question: should you add a flexo printing machine, go all‑in with digital printing, or consider both production pa

Register marks are the “eyes” of the automatic registration system in CI flexo printing. They tell the sensors where each color plate is, allowing the system to adjust register between color stations in real time.

Let's be honest—if you make paper cups or bags, picking a flexo press is never fun. Every brochure says the same thing. Prices jump all over the place. And whatever you choose, you're stuck with it for years. Paper's tricky—it stretches, absorbs ink differently, and coated stock needs extra care. Plus, cups and bags have to be food-safe, look good, and run in high volumes. So here's what actually counts—no fluff.

In flexible packaging flexography, thin‑gauge films—especially 30–50 micron polyethylene (PE)—are among the most challenging substrates to print. These films are extremely sensitive to impression pressure:

In CI flexo printing, the anilox roll is often called the “heart” of the press. How well that heart beats determines print quality – solid density, highlight dot retention, and edge sharpness of text. Yet, faced with numerous combinations

Gear marks are among the most frustrating print quality defects in flexographic printing. They appear as periodic light–dark streaks that match the gear pitch, usually spanning the full web width and running perpendicular to the web direction.

You're running a long job, everything seems dialed in—then suddenly, your solids start looking patchy. Dots are skipping. The print has that dreaded “snowflake” or mottled appearance that

If you’ve ever seen those frustrating light “ghosts” on your CI flexo press—a faint shadow behind a solid area, or repeating patterns that show up like clockwork—you know how maddening it can be.

Choosing the right flexographic printing press is a critical decision that directly impacts your product quality, operational efficiency, and material waste. For plant managers and equipment selection teams, the debate often narrows down to two dominant architectures: stack-type and central impression (CI) flexo presses.
