You may encounter a Low-Resolution warning displayed on the screen in Silhouette Studio, indicated by a yellow warning symbol in the upper left-hand corner of your design area:
This is not an error message. This message is an on-screen prompt to warn you that the print quality of the image may be less than desirable. This warning is the software trying to guess the potential resulting print quality. It is more of a guideline than a definitive message to indicate that there will actually be any problem.
NOTE: If you are concerned that your print quality may be too low, print a test sheet on a sheet of copy paper. If you are happy with the results, you can safely proceed to print onto your actual target material. If you are not happy with the print quality, you may need to consider resizing the image to a smaller size for better printing performance.
