What you see on your screen is often different than what you see on paper. That’s because your screen is backlit and paper is not. Expect screen colors to appear duller, lacking in contrast, and variances in color shades when printed.
The paper will slightly move during the cutting process which will affect the alignment of your final print. This is normal in the printing process. The alignment of your artwork on the paper may vary within the tolerable margin of error. Adding a bleed to your artwork, avoiding using borders, and keeping all important elements within the safe area will keep your artwork legible even if there is a shift.
