The article provided has useful information on ensuring a safe label press run by making the right choices when preparing sleeves and plates for mounting. Let’s delve into the details and expand on the topic for a more comprehensive understanding.
Making Informed Choices
Label press operations, whether involving a few cylinders or numerous wide web sleeves daily, demand meticulous preparation to achieve optimal print results. Properly mounting cylinders and sleeves significantly influences the printing outcome. Key factors in sleeve and plate preparation are essential for a hassle-free printing process. Here, we concentrate on the sleeve’s pre-mounting preparation to facilitate a secure label press run.
Importance of Cleaning Sleeves or Cylinders
For a plate mounting tape to adhere effectively to the desired surface, ensuring cleanliness is paramount. Cleaning entails the removal of adhesive, liquid, ink, and dust residues. The recommended cleaning agent is Alcohol/Isopropanol or a 50/50 mixture with water. In urgent situations, Ethyl acetate can suffice; however, allow it to air dry for a minimum of 5 minutes post-cleaning.
Significant Considerations: Sleeves typically feature minute scratches on their surfaces. Solvents used during cleaning penetrate these grooves and necessitate adequate drying time. Premature tape mounting before solvent evaporation can lead to trapped air beneath the tape, causing unsightly bubbles within 30-60 minutes of application, an outcome undesired by press operators.
Step-by-Step Workflow for Sleeve Preparation
- Cleaning Process: Utilise a suitable solvent for cleaning the sleeve, ideal immediately after a press run for optimal results.
- Drying Stage: Allow solvents to air dry for a minimum of 5 minutes to ensure complete evaporation.
- Tape Mounting: Employ a rubber blade or pressure roller system within a plate mounter for precise tape application.
Once sleeves undergo this meticulous cleaning and preparation, they are primed for the subsequent step – Plate mounting. However, before delving deeper into this phase, a thorough exploration of tapes and their suitability concerning print parameters is necessary. This extensive segment will systematically address considerations related to print design, plates, sleeves, and substrates, key components essential for a successful label press run.
