Most ...I'm impressed that you print in 300dpi! Most print only in 150-200 dpi. Kudos to your company! That's rare!<br /><br />But, dpi and ppi is not the same at all. google it. dpi is an OLD term that has been applied to everything relating to resolution incorrectly and that's why it confuses people who want to print, say scrapbook pages or art for example. New technology has made us more aware. No longer do we just hand you a roll of film to print… we are creating our own pictures our way in every form of art there is! :) <br /><br />Basically if they create the size of print they want in inches (say 12x12), then they need to create their image in 300 ppi (or 3,600x3,600 ppi) in their graphics program. <br />Screen resolution has nothing to do with what I was talking about sorry if you thought that. <br /><br /> I create and print art and photographs all the time and get asked the question over and over because a printer will say something like "your picture needs to be such and such size dpi." Our graphics programs work in ppi NOT dpi, and this leaves the most common users not knowing what to do. <br /><br />My wish would be for a printer to convey to the customer that if they want a good quality print, then they need to have 300 ppi in their graphics programs. So a 12x12" output size needs to be 3,600 ppi square. <br /><br />But I will say that I will be trying your product if you print in that high of a dpi!

Dpi refers to the out put of the machine you are printing on. Our machine prints at 300 dpi. The files technically are made from pixels, so they call it pixels per inch. Ink jet machines need to print at a much higher dpi then our machine to get the same quality.<br />-KennyKenny Joneshttp://www.persnicketyprints.comnoreply@blogger.comtag:blogger.com,1999:blog-2294286164729020318.post-44480602610535920152010-09-23T22:17:08.532-06:002010-09-23T22:17:08.532-06:00Dots per inch (DPI) in this context, refers to the...Dots per inch (DPI) in this context, refers to the smallest amount of ink that a given printer can print. Put another way, the more dots that a printer (or imagesetter) can apply per inch, the higher the resolution (and therefore quality of image reproduction) an imaging device can reproduce.<br />We don't use ink at Persnickety Prints.<br /><br />Pixels per inch (PPI) is often used interchangeably with DPI. PPI is, arguably, where the confusion started from in the first place. PPI a somewhat relative term. Once a photograph is opened in a program such as Adobe Photoshop and displayed on a computer screen, its relation to print paradigm concepts such as per inch are not always helpful. In many cases it is actually more helpful to talk about the total width and height of the digital image in pixels, rather than pixels per inch or dots per inch.<br /><br />For printed reproduction, the amount of dots per inch only becomes relevant when calculating the amount of digital information against the intended output size of the image. For example, if the printed requirement of an image is 300dpi, to be output via a 150 line screen, then an image that is 1500 pixels wide and 800 pixels in depth can be printed at a size of 127mm by 67.73mm. Changing the resolution to 350dpi for a 175 line screen printing job, reduces the acceptable output size to 108.86mm by 58.06mm, however the actual dimensions of the on-screen image remain the same – 1500 pixels by 800 pixels.<br /><br />Note that we are not talking about resampling the image here, which is different in that it involves actually either reducing or adding information to the image, rather than simply defining its attributes from the digital world to the print paradigm.<br /><br />For on-screen use, such as web design, the PPI of an image is largely irrelevant. It is the PPI of the computer screen which defines the display size of an image on screen. For example images on a 96dpi monitor, will display slightly smaller than those on a 72dpi monitor.Persnickety Printshttps://www.blogger.com/profile/15515254231161699956noreply@blogger.comtag:blogger.com,1999:blog-2294286164729020318.post-61521583944129640932010-09-23T07:17:00.606-06:002010-09-23T07:17:00.606-06:00Great article… except as most do, you are mixing u...Great article… except as most do, you are mixing up DPI and PPI.<br />300 PPI = 150 DPI (approximately depending on the printer and settings used).<br /><br />DPI is what a printer uses to translate. Dots per inch as you say.<br />But PPI is what your programs use and your screen on your computer sees.

We tell our photography students to set their cameras on the highest settings, with the least compression. If they want to get more pictures on their card, just buy a bigger or another card. Cards have gotten cheap enough that there's no reason to settle for lower resolution images. You never know when you want that one amazing photo to fill a 12x12 layout, or will want to zoom in to that funny face in the background!!Jennwhitehttps://www.blogger.com/profile/13058690307851087073noreply@blogger.com
