Compression rates of 100:1 can be achieved, although the loss is noticeable at that level. JPEG involves a lossy compression mechanism using discrete cosine transform (DCT). JPEG is a joint standard of the International Telecommunications Union (ITU-T T.81) and the International Organization for Standardization (ISO 10918-1). JPG is a graphical file format for editing still images, it offers a symmetrical compression technique which is processor intensive and time consiming in both compression and decompression. The JPG file is a great format as it often manages to compress files to 1/10 of the size of the original file which is especially good for saving on bandwidth. The JPG format is often used in digital camera memory cards. The resultant 'lossy' file means that quality can never be recovered. That your Photoshop file is a 300ppi, try to insert 300ppi in theĪcrobat resolution setting.JPG's are often used for web sites and email as they are generally smaller file sizes as they are lossy meaning that some image quality is lost when the JPG is compressed and saved. If you want to see the exact same size in Acrobat and Photoshop, and I'm not certain but I think by default it's possible your page display is set to the system setting. The example on the right is using 72ppi display resolution in Acrobat and the one on the left is using 101ppi. It's also normalįor example, the example below are the exact same PDF at 500% in Acrobat. One reason why your PDF could look like being a different size than the Photoshop is the resolution set in the Adobe Acrobat Preferences.ĭepending on what you have there, the "real size" of your PDF will vary on the screen. But you seem to have understood this already. This is slightly destructive, it's good for some situations but if you can, it's better to convert your PDF to vector or use the first option above.Īcrobat doesn't open by default at 100% or fit to page it depends on your preferences or the setting in the PDF as well. Usually 2 gives good results.ĭon't forget to keep another version of your Photoshop with layers trapping like this will require your to flatten your file and you also need to be in CMYK color mode! In this box, add 1 or 2 pixels of trapping. To do this, go on the menu "image" and select "trap". It doesn't do miracles and your text and whole layout will still be a raster image. This will hide the anti-aliasing you might see on the final result but it will not improve the quality of your file Some colors don't blend well together and this will at least hide a bit the effect of anti-aliasing between the colors.

If you don't own a license of Illustrator or simply don't want to use it, or you're using an older version of Photoshop, you could try to add some pixels to your trapping on your text. Other Option: Add some trapping in Photoshop "Adobe PDF file too big, what are my options?" If you're satisfied, you can follow these instruction to optimize your PDF to be a smaller file size but retain the same print quality: Now export that PDF with the highest quality setting or no compression at all, and open it again the way you took your screenshots to see if the issue still happens.
#BLURRY IMAGE CONVERT DOC TO PDF MAC HOW TO#
How to keep the text in vector in Photoshop without rasterizing it or flattening the layers when exporting to PDF? Choose the "convert layers to objects" and your text layers from Photoshop will be transformed into vectors. psd with the layers, and open that file in Illustrator. Second Option: Convert that Photoshop text to vector The examples below are both screenshots from Acrobat PDF:
You can keep the same settings for compression as the ones you already mentioned. When you flatten the whole layout before exporting, it rasterizes everything together. This way you will keep the "vector" properties of your text depending on the Photoshop version you use. Let Photoshop flatten the layers during the export by checking the "as a copy" box while you export in PDF. You can fix this in 2 ways:įirst Option: Don't flatten the text layers in Photoshop before exporting!
If the texts are blurry, you can cheat and convert your PSD layer file to PDF, and still keep the sharpness of a vector.įrom the screenshot that is still visible, it looks like a question of text trapping in Photoshop.
But let's assume your images have the right resolution and were not resized bigger, or didn't lose any quality in that way. It's unclear if your issue is the text being blurry or the images.
