Disabling the line weights can make it easier to see your lines, allowing you to make precise selections and measurements. However, if weighted lines overlap, for example, it may become difficult to differentiate between them when performing measurements or takeoffs. In most cases, line weights lines are useful when looking at your drawing because they allow you to see the different styles and types of lines in your drawing. Your designers (and clients) will thank you.Line weights are enabled by default. loss of spot colors, font hinting, etc).īottom line - if you have a PDF, print it from Acrobat or InDesign (or Illustrator). This is silly behavior and can cause numerous other problems in the PDF (i.e. I've seen "smart" prepress operators think that due to the white lines they see in Acrobat, it's better to open the file in PS instead and then apply blurs or other effects to try and "get rid" of the white lines. In that case, depending on how the file is saved from Photoshop, those white lines could get baked into the file itself (as once the file is in Photoshop, it's all converted to pixels). Perhaps because they think this is better. HOWEVER, there are those (evil people) who will choose to open your PDF file in Photoshop. If that's the case, all is right in the world and your clients will sing your praises (although they will surely still only want to pay you barely minimum wage). The assumption is that the person who receives your file will open the PDF in Acrobat (or place it into InDesign) and then print it from there. Sending a validated PDF/X-1a file is the best way to submit files to someone else when they are going to print it. How? OK, let's assume this scenario - you create an ad in InDesign or Illustrator and create a PDF/X-1a file. If you have additional questions about either of these issues, don't hesitate to drop a comment into this post or the YouTube link.īy the way, I didn't mention this in the video clip above, but it's POSSIBLE that you could see these white lines appear in print. The two culprits in this case are Smooth Line Art and Enhance Thin Lines.įor a more in-depth understanding of when these issues occur, why they occur, and how to adjust your settings to get rid of them, I recorded this 12-minute clip for your viewing pleasure: You can easily get rid of the side effects (the white lines and the fat lines) by disabling the specific antialiasing settings that introduce them - directly in Adobe Acrobat Preferences. It's like any medication - it aims to solve one thing, but often can introduce side effects. It solves some problems (gets rid of the jaggies), but it can also introduce other issues (on-screen artifacts). As I explained in this previous post, antialiasing is a double-edged sword. Both of these screen artifacts (and they are just that - screen artifacts - they don't show up in print) are caused by the same culprit - antialiasing. Many people experience this issue, along with another good one - seeing white lines within PDF files. My client: "Your pdfs make the “l” (el) look bold." Hey will you ever fix this preview bug? It's nearly a decade old now. My good friend Von Glitschka posted the following tweet the other day:
