class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Image formats differ along two key dimensions:<\/p>\n<ol>\n<li>Vector vs. raster<\/li>\n<li>Lossy vs. lossless compression<\/li>\n<\/ol>\n<p>Vector formats (e.g., EPS, PDF, SVG) store images as mathematical descriptions and scale without loss of quality. Raster formats (e.g., TIFF, JPG, PNG) store images as pixels and depend on resolution and dots per inch (dpi) at final print size.<\/p>\n<p>Publishers convert submitted figures into production-ready PDFs and printing color spaces. Choosing the wrong format or compression level increases the risk of blurred labels, jagged lines, and replacement requests during production.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Key_Concepts_Vector_vs_Raster_Color_Spaces_DPI_Compression\"><\/span><strong>Key Concepts: Vector vs. Raster, Color Spaces, DPI, Compression<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li><strong>Vector images<\/strong><br \/>\nStore shapes, lines, and fonts mathematically; resolution independent and ideal for charts, schematics, and chemical structures. Save as EPS or PDF with fonts embedded or text converted to paths.<\/li>\n<li><strong>Raster images<\/strong><br \/>\nStore pixels; quality depends on pixel dimensions and dpi at final print size. Always verify dpi at the final output size.<\/li>\n<li><strong>Color spaces<\/strong><br \/>\nMost journals request RGB or grayscale at submission and convert to CMYK for print. PNG does not support CMYK natively, which can limit print workflows.<\/li>\n<li><strong>Compression<\/strong><br \/>\nLossless compression (TIFF with LZW\/ZIP, PNG) preserves all data.
