You may encounter a Low Resolution warning displayed on screen in Silhouette Studio, indicated by a yellow warning symbol in the upper left-hand corner of your design area:
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.
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 re-sizing the image to smaller sizing for better printing performance.
