Screen printing remains a fantastic technique for producing custom clothing. However, creating designs while dealing with the need to eliminate ink stains creates a big hassle. Proper cleaning procedures for screens matter because they lead to superior print quality and longer-lasting operation of your equipment regardless of ink type – plastisol or water-based ink. This article provides step-by-step directions on advanced methods for cleaning screen printing screens.
Can Screen Printing Ink Be Removed?
Yes, screen printing ink can be removed by using a quality screen printing cleaner. The cleaning process for screen printing ink depends on the specific formula of the chosen ink. Screen printing inks primarily consist of plastisol ink and water-based ink, which demand dissimilar cleaning methods. Plastisol ink works as an oil-based product only when heated until it achieves dryness. The material retains water-based ink on its surface for multiple hours without drying before you can eliminate it using proper screen printing cleaning agents.
Will Screen Printing Ink Wash Out?
Plastisol ink requires heat treatment to achieve longevity because it serves as screen printing ink that must resist washing. The ink stain might be removable by soap and water when it is still fresh before heat curing takes place. These cleaning agents dissolve ink particles, making it possible to wipe off the stains without causing any damage to your screen.
How to Remove Off-Screen Printing Ink? Step-by-Step Guide
Screen cleaning requires proper attention because it protects your print quality and prevents ink accumulation. The procedure below guides users through the effective removal of plastisol together with water-based ink.
Step 1: Gather Your Cleaning Supplies
Before you start cleaning, make sure you have the following items:
- Screen printing cleaner (designed for plastisol or water-based ink)
- Press wash or screen wash
- A soft brush or rag
- Emulsion remover (if you need to reclaim the screen)
- Gloves and protective eyewear
- Plastisol ink remover
Step 2: Remove Excess Ink
When done with a print run, use a squeegee or a spatula and remove any excess ink from the screen. It facilitates easier cleaning and avoids the waste of unwanted ink.
Step 3: Apply the Screen Print Ink Remover
On the basis of the ink that you have employed, select a corresponding screen print ink remover:
For plastisol ink: Use a plastisol ink remover or a plastisol ink-specific screen wash. Put it on the screen and allow it to sit for a few minutes to soften the ink.
- For water-based ink: A screen wash made specifically for water-based ink will perform best. These solutions penetrate into the ink and break it down effectively.
Step 4: Scrub and Wipe Clean
Scrub the screen in a circular motion with a soft brush or rag, removing all ink scraped off the mesh. Don’t damage the screen or stencil.
Step 5: Rinse with Water
After removing all ink, rinse the screen in warm water. If there is still some ink residue, repeat the same process until the screen is clean.
Step 6: Dry and Store the Screen Correctly
Once cleaned, let the screen dry completely in the air before reuse or storage.
Plastisol Ink vs. Water-Based Ink: Which is Easier to Clean?
When working with plastisol ink in comparison to water-based ink, cleaning procedures show specific differences.
- Plastisol ink becomes easily cleanable without heat curing. Use a press wash together with plastisol ink remover to remove the ink through wiping. Plastisol ink achieves a permanent cure after the curing process ends.
- Water-based ink becomes stubborn to remove from the screen printers because it dries quickly. The screen mesh requires immediate cleaning during printing, or the ink will enter its mesh structure.
Which One Should You Use?
Customers seeking simple cleaning processes combined with durable prints should choose plastisol ink. For customers needing sustainable inking solutions that retain fabric softness, water-based ink is the proper choice.
