4-color process inks are designed to be transparent so they will create other colors when they are overlapped. When these very transparent inks, without a white back up, are printed on a clear material to create a decal that will go in a window the whole imprint just disappears. By backing the 4-color process printing with white we can define and present a process image without losing any detail or color on an inside window decal.
Generally, images used on a web page are 72 dpi. They are so low in resolution to help speed the loading of a page on a computer. Industry standards say to use twice the resolution as the line tone being printed. Since screen print is done at 100 line tone we need scanned digital images at 200 dpi resolution. Flexo and letterpress items are printed at 150 and 133 line tones so we would need images at 300 resolution. There are places online to purchase high resolution files or a high resolution image can be placed on a web page for use by others. It will just not copy or load as fast.
EPS and TIFF are file formats or ways that a file can be saved. EPS is a generic format that allows information to easily be transferred between different programs and from a program to an imagesetter. EPS files cannot be edited, in other words, we could not change the image or change the text, we generally can, however, resize an EPS file. TIFF is a format for a scanned image. It also easily transfers information from one program to another. However, a TIFF file is just a "picture" of the art and is not made up of the individual elements of vector art as in an EPS file.
Nine square inches is our general guideline for a custom size domed decal. However, because the cutting and doming process can be complicated on this item, there are several considerations when preparing a quote.
No, we actually deboss (push down) the background color on a label and then as a reaction the copy is embossed (raised up). In order to get the color to adhere to the material we use heat and pressure. Since the pressure is applied to the background it is the only area that will be a color. The copy cannot be embossed as a color.
No. If a label is perforated, we cannot strip the waste because the tension is very high on the roll of waste material as it is pulled off while on the press. This tension tends to break the web.
The line left by the slitting process is actually a mark left in the adhesive, not on the material itself. However, the adhesive will continue to flow and that line should eventually disappear. The soap and water application method is another way to aid the flow of the adhesive to eliminate any slitting marks. The only way to avoid the mark caused by slitting on clear decals is to not slit the decal at all but then you have lost the benefit of a split release liner for easier application.
