A&E AUGUST 2017 • 57 Second, understand how to adjust your artwork for the absolute best etched design. It is important to handle the difficult design from the beginning when you're in the approval process. Adjusting your artwork correctly also makes it easier to produce your mask and sandcarve without any glitches, especially in a production run. Today, our customers want detailed images, and we manufacturers push the envelope of detail in our photoresist film. Photoresist film can handle detailed art- work, but often the job requires deep etch. Adjustments to detailed artwork are then required when sandcarving more than a surface etch. Your graphics program is perfect for cor- recting your artwork. The goal is having a design approved for sandcarving—this may be as simple as adding a stroke to the thin lines in the design. If a deep etch is required with a detailed design, you may need to simplify the design. The simplified design will look better as a sandcarved image. ARTWORK ADJUSTMENTS See the example of original versus adjusted artwork on page ?. This printed artwork is an element from a wine label and looks great as a printed label. This par- ticular job required a deep etch for paint-fill application, but some of the lines were too small and thin to hold for a deep etch. Our Custom Mask department adjusted this artwork. You can see the adjustments in the two images. Image 1 – Original Artwork There are thin lines in the crest. The birds have several little lines in the body, which are barely visible in the photomask and will not look good etched. Image 2 – Adjusted Artwork Our graphic artist adjusted the artwork by adding a stroke to the thin lines and removing some of the detail. They also made the birds into silhouettes, making the bird shape much more visible in the etching. This adjustment allowed for a deeper etch in all the detailed areas and provided the resolution that the design needed for the etching. Both designs were sandcarved with alu- minum oxide 150 grit at 40 psi. Typically, production etchers will sandcarve at much higher psi to move through the etching quicker. You can see the difference in the etching on page 56. One design appears sharper and providing a resolution similar to the printed label. Image 3 – Original Artwork Sandcarved The birds are not visible. The details in the lines do not show up well etched. Image 4 – Adjusted Artwork Sandcarved See image on page 58. The birds are visible and actually stand out. There is definition between the lines, allowing the crest to etch deep. The two forms of artwork when blasted; notice the difference in details and readability of the design.
