All About Picture Sizes

Ever since we used up all the toner of our HP Laserjet 1020, Innerchild Computer System (our little business partnership with my brother Nelson) has less revenue compared to the first few months of operations.

I need a approximately Php6,000 for a colored printer (Epson C79 or C90 or something) and for the Continuous Ink System (CIS). We wanted to offer photo printing services for our customer and having a CIS is the most efficient way to do it (based on hear say blah blah).

The thing is, I may need to do a little work on finding out what photo resolution fits on a standard picture size. Example, which resolution best fix on a wallet size picture, or the best resolution for an 4R? an 5R? Now that we’ve mentioned it, what the heck in an ‘R’ in 4R or 5R? Or how about the pricing? how much would the printing cost be?
First, here are fast answer to my question:

Print | Size Min. | Resolution (Pixels)
3R (3″ x 5″) 640 x 480
4R (4″ x 6″) 1024 x 768
5R (5″ x 7″) 1280 x 1024
6R (6″ x 8″) 1600 x 1200
8R (8″ x 10″) 1800 x 1200

Or here’s a reference….

The price for photo printing is different in a studio and in a Computer/Internet Cafe.

Here’s how the Lanshop owners’ say about it:

• For 3R, or wallet size pictures, printing is Php12
• 4R – Php 15.00
• 5R – Php 20.00
• 8R – Php 50 (or P80 if you’re greedy enough)

And those are for glossy photo paper… What if the customer only wants it to be printed in an ordinary bond paper?

Well, I say minus Php 2.00 :-)

Here’s an additional info about the meaning of the 3R, 4R, 8R thingy….

Standard photographic print sizes are often denoted with a code of the format nR, where the number n represents the length of the shorter edge in inches. In the normal series, the long edge is the length of the short edge plus 2 inches (10″ or less) or 3 inches (11″ and above).

There! Now you know… We still don’t know that the ‘R’ in 4R is. So what is it?
