Author Increase Print Size of .jpg graphic
Ed Schwing

2004-12-19, 7:14 pm



Please excuse what is probably an elementary question; however, how can I
double the size of a .jpg graphic without getting jaggies? The particular
graphic is 2" X 1 1/2" in size, and I would, if possible like to double the
print size. I am using PS CS. I attempted to use the resize option and it
was a mess. Hopefully someone of you can help me in a manner that this 75
year old will understand. Thanks in advance . . . . . Ed

THe problem us that all resizing, especially resizing up degrades
quality. Try using Bicubic Smoother in Image Size.

In Photoshop

Go to the menu bar at the top and select IMAGE then use the drop down
palette to select IMAGE SIZE

A dialog box will open.

Make sure that the boxes are checked for Constrain Proportions and Resample
Image.

Make sure that Bicubic is selected next to Resample Image. (If it is not,
click on the arrows and select it.

In the box for resolution it probably has 72 for pixels/inch. Change that
to 144 for an ink jet printer.

At the top, there are two boxes for Pixel Dimensions. Click on the arrows
and select PERCENT then type 200 for the Width and Height.

Click OK and you should be ok.

Save the file if you want to print it again or place the enlarged file in
another document.

Good luck.

As edjh posted just 5 minutes before you: it better to use Bicubic
Smoother for upsizing.

Go to Image/Image Size...

At the bottom of the dialogue, select (i.e., make checks) in both boxes:
"constrain proportions" _and_ "resample image"

In the menu next to "resample image", chose "Bicubic" (in order to avoid
jaggies).

In Document Size, enter the print resolution (ppi) that you desire
(e.g., some number between 150 and 300 ppi); and...

also enter whatever value (probably in inches) that you want for the
new, larger print dimension. Just need to enter a value for either the
width _or_ the height.

Print
