    Printing graphics - resultant size

    Occasionally I come upon some result that makes me question whether what I had always supposed was true is actually true!

    I am taking a graphic JPEG image which shows in Windows Explorer as being 600 pixels wide
    importing it (Insert -> Picture -> From File) into an entirely blank Word (2002 SP3, if it makes any odds) document
    then printing it on three different (HP) printers.

    When I measure the resulting printed image width, I find that it is ~1.85" on all three printers, whereas I was expecting it to be as close as possible to 2.00" (300 dots per inch, of course).

    I then set up a new document in Courier New 12-point (i.e. ten characters per inch) and did a series of (vertical bar | followed by nine spaces), so that the vertical bars were exactly an inch apart. Printing this document showed that a 6" wide section of this line measured exactly 6" on the ruler I had used for the first exercise.

    The difference between the actual image width, 1.85", and the expected width, 2.00", namely 7.5% or 8.1%, depending upon which way you do the calculation, seems to be too large for an experimental error.

    Can anyone explain what's going on?

    Thanks

    John

    PS If you want to know the purpose of this exercise, I was trying to size a graphic image so that it would print exactly 2" wide...!

    When you open the jpg file in Paint and select Image | Attributes, what is reported as the size and as the horizontal and vertical dpi?

    The size is 104,152 bytes (?) and the resolution is 300 x 300 dots per inch...

    Re: Printing graphics - resultant size

    Could it be the background is being included in the image size ??? If you crop the image so that there is no background outside the image itself, does that change the attributes ???

    I meant width x height, but I suppose it'll report 600 pixels wide.

    Re: Printing graphics - resultant size

    When you have imported the picture into Word and look at it's properties (Format Picture), what size and scale is shown?

    Re: Printing graphics - resultant size

    I'm not at work anymore today, but I think Doc might well have solved the mystery, with his suggestion of a (small) border round the image. I will check on this tomorrow, and also on Leif's idea. Thanks!

    Re: Printing graphics - resultant size

    You know how you can use a program for ages and not have any idea how many different functions and how much information the program makes available if you know where to look ??? I've been inserting pictures into Word since I first started using it and formatting those pictures and wrapping text around them and never once did I click th Size tab !!! <img src=/S/bingo.gif border=0 alt=bingo width=15 height=22>

    Thanks for opening that door in Windows er, Word for me Leif. <img src=/S/smile.gif border=0 alt=smile width=15 height=15>

    Re: Printing graphics - resultant size

    Yes, as Doc suggested, the problem has was a fairly thin and unnoticed border (about 20 pixels each side). I have done some cropping and resizing, and the printed width is now, magically, almost exactly 2".

    Thanks to everyone for their help.

    > almost exactly 2"

    So which was it?
    Almost 2" or exactly 2"?
