![]() The default Illustrator PDF/X-4 preset downsampled the 800ppi image to 300ppi, and the 160% scale in InDesign further reduced the Effective res to 187ppi. The X4 version fails preflight and the AI version passes because of the 160% scale. Here's an example where I placed identical files saved as AI and default X4 in InDesign. AI.Īctually there are a number of demonstrable problems with X4 besides the need to maintain two documents, which is a non starter for me. This has come up before and no one seems to be able to show how a PDF/X-4 would produce higher quality output than. The only exceptions to this are the situations in which (1) text must be converted to outlines to yield extraordinary special artistic effects and/or (2) an SVG version of the logo must be made for web or Office use - font specification and use in SVG isn't particularly consistent and/or safe! ![]() Logo quality is definitely better with live text. Yes, I know that many graphic artists have been brainwashed into believing that fonts should not be embedded in logo file assets such as PDF or even EPS, but the facts are the facts. Such live text ensures the highest quality rendering of the text aspect of the logo, especially at smaller sizes. I will further note that for logos in which there is any text, the text should remain as live text for the PDF version of same, making sure of course that the font is properly subset-embedded in the PDF file of the logo. A logo in vector SVG format will render with much higher quality than a logo as a raster image (TIFF, PNG, or gasp, JPEG). Recent versions of Microsoft Office can indeed properly import SVG graphics. A better solution for Office import would be a totally vector version of the logo saved as SVG. (2) The logo designer was directed to output a raster version of the logo such that retrograde software such as Microsoft Office applications could use the logo. And even if only text and vector content is used in Photoshop for creating a logo, unless one preserves that text and vector layers and saves PDF from Photoshop, output will likely be raster image only at whatever resolution the artwork was initially created at. With rare exceptions, of Adobe products, Illustrator and InDesign are much better for logo design than Photoshop. (1) The logo designer is most proficient in Photoshop and uses Photoshop for everything even when such usage is inappropriate. There are two reasons why logos as raster images pollute the publishing landscape: In reality, very few logos require raster image content. Logos in raster image format are effectively rendering device resolution-dependent. Some general advice: Corporate / organization logos should be rendered as vector or vector/text for highest quality reproduction in any context. Although the OP indicates that the logo file is EPS and “it is still 300dpi” there is no explicit statement that the content of this logo is raster image, vector, or some combination of same. One critical issue that has not been answered directly by the OP is exactly how the logo was created and what type of content it contains.
