Limitations of Using Adobe Illustrator to Edit PDF: Similarly, the images can be edited in a PDF file. You can also select the text and replace it with the new text.
Then John makes the assumption that if you print to scale that Illustrator will do something to the file other than just print the same information at a different dimension and not a different file size. There is a difference with printing large scale for fine art and printing for display and the resolution today as opposed to the past is the same perhaps it has actually improved today. When I was 19 I worked for an ad agency where we on occasion printed 24 sheet posters at something like 20 dpi it took up a whole empty floor of the office building to piece it together you left out sections where the columns where we just wanted to make sure they printed all the pieces.
This is not new to digital age as i started in this business when I was 16 years old and use to help my step brother on occasion at the new york post where the resolution of the printed piece was 60 dpi and that was for all images in the paper, which looked perfectly fine to everyone since it was only a newspaper. The reason fo this is that this about communications and not about resolution.
There are certain devices that will require 255 ppi resolution of a file to properly output such as a Lambda or Lightjet for a fine art digital C print.īut In commercial printing it has never been the case the main reason is that for commercial printing you need a space between the viewer and the printed piece in order for them to be able to read the text and see the visual. I am afraid John is putting oranges and apples together and calling them grapes.
