Avoid using low-resolution images (below 300 DPI) when printing a book, as they may appear pixelated. Don’t neglect to proofread thoroughly; typos and formatting errors can detract from professionalism. The printing experts at any online printing services in UAE should avoid choosing inappropriate paper quality or weight for your book’s genre—lightweight paper may feel cheap, while heavy paper can make the book cumbersome. Don't ignore bleed margins; ensure text and images don’t get cut off during trimming. Avoid inconsistent fonts or excessive font styles, which can make the book look unpolished. Lastly, don’t skip a test print; reviewing a physical proof can reveal issues not visible on the screen.
