hello every one,
There has been a lot of depate going on as i met a person who works for Kodak and they are telling every one that One can not see above 4800DPI.. so i though to place a topic here to get the word out and we can have healthy discussion regarding this topic..
When printing we need to keep following things in mind.
2. PPI (pixels per Inches)
3. DPI (Drop per inches)
1. Megapixles is the resolution of your camera Mega stands for Million
2. PPI is the number of Pixels per inches.. This value has its limit up to 300PPI when we reffer to Inkjet printers
3. DPI the drops placed per inch.
The term DPI is often used interchangably with PPI, causing a lot of confusion, however, DPI refers to the resolution of the printing device, where PPI refers to the resolution of the image itself.
Now, Many people say you can not see above 300PPI. many printers have offered high DPI, the printers with high DPI values like 4800dpi or with canon 9600dpi refers to how smooth your image will be.. Printers places to many droplets to show one particular pixel in its certain colour..
so, the higher the number is the more smoother the picture would look..
Now, many companies also says that havig so many droplets may just overlap one another at that certain square inch.. Apparantely on all the printers boxes you can see the droplet size the printer is producing, with EPSON its 1.6pl (pl stands for Pico litre) with canon its 1pl.. HP with certain printers uses 2pl.. so these small droplets dont really overlap one another.. and saves ink consumption as well in one sence..
on a 8MP DSLR i can print up to A3 easily.. which is 11.7 x 16.9 "
3264 x 2448 10.88" x 8.16" from 300 PPI..
3264/300 = 10.88
2448/300 = 8.16
We can print bigger size by Resizing our pixels using softwares like Adobe photoshop..
Hope this article would have helped you..
