What Are the Key Steps in Screen Printing Screen Exposure?
Creativity comes from the mind and its beautiful thought process. Mastering any art in OKC & beyond demands a keen understanding of the intricate factors that influence the outcome. The process of screen printing is no exception. Check out the intricate factors in detail.
Additionally, discover how other factors like vacuum blankets, mesh color, and halftones LPI count play a pivotal role in refining screen printing in OKC.
What Are the Factors That Influence Screen Printing?
Mesh Count
Mesh count significantly affects screen printing exposure time. A 110-mesh screen retains more emulsion due to larger openings, necessitating longer exposure times compared to a 305-mesh screen. This abundance of emulsion in a 110-mesh screen results in slightly longer exposure times. Mesh count also impacts image resolution and ink deposit: higher counts yield finer details and smoother prints, while lower counts are ideal for thicker ink deposits and more prominent designs. Selecting the proper mesh count is crucial for achieving desired results in screen printing projects.
Emulsion
In screen printing, three primary emulsion varieties are used: photopolymer, diazo, and dual cure. Dual-cure emulsion is beginner-friendly, with a forgiving exposure "window" for desirable results. Photopolymer emulsion offers fast exposure but has a smaller tolerance window, requiring precision. Diazo emulsion provides an alternative, with an exposure window comparable to dual cure. Understanding these emulsion differences is crucial when selecting the right option for screen printing projects.
LED Exposure
The light source is crucial in screen printing outcomes. Professional-grade LED exposure units provide even light distribution, unlike floodlights. However, floodlights can still work effectively. Consider factors like bulb intensity, as the light source weakens over time, requiring exposure time adjustments. LED sources are durable, maintaining strength for 3-5 years. Selecting the right light source and monitoring performance are vital for optimal screen printing results.
Additional Factors To be Considered!
Adding a vacuum blanket to your exposure unit is highly advisable for screen printing. This accessory ensures that the screen mesh remains tightly pressed against the film positively, promoting higher resolution in your stencils. Alongside this, there are three other vital variables influencing screen and stencil production during the exposure process.
Mesh color and halftones LPI count are additional factors to consider. It's been suggested that yellow mesh may offer better results compared to white mesh due to its ability to trap light, thereby reducing light bouncing and minimizing undercutting. Regardless of the specific emulsion, mesh count, mesh color, and light source employed in your screen printing workflow, utilizing an exposure calculator can be immensely beneficial for fine-tuning your screen exposure times.
