| Posted: | | | | Hi everyone,
I am looking for a site to download high res images of movies posters, I am thinking about printing them on canvas but not full size. I want to put smaller versions of movies poster on my walls so I can put more of them up.
Can anybody help me out?
Thanks. |

| Posted: | | | | You can check out www.impawards.comKeep in mind that for printing it's not only width and height that is important. For printing, the image resolution also depends on the dpi (dots per inch value). Often for images on the web, this is only 72dpi. Ideally, you need 300dpi. For larger viewing distances, you can use lower dpi images. 2 ft --> 225dpi 4 ft --> 140dpi 8 ft --> 80dpi | | | View my collection at http://www.chriskepolis.be/home/dvd.htm

2 ft --> 225dpi 4 ft --> 140dpi 8 ft --> 80dpi Where's the difference between 6000x4000px in 72dpi against 6000x4000px in 1200dpi in a your image when printed in the same size? | | | |

| Posted: | | | | Suppose you print a document for viewing in a book, which is close range.
6000x4000 is your screen resolution, and viewing a 72dpi or 300 dpi image on a computer screen will show no difference. The DPI is the print resolution. If you print a 72dpi document at 300 dpi, your pixel size will be increased, resulting in quality loss.
If your document is 6000x4000 at 300 dpi, you can calculate the maximum printsize. Since you need 300 dots per inch, dividing de image size by 300, gives you a maximum print size of:
20 x 13.3 inches. | | | View my collection at http://www.chriskepolis.be/home/dvd.htm

20 x 13.3 inches. 6000x4000px in 72dpi is the same as 6000x4000px in 600dpi. Since it's always 6000x4000px in 300dpi when you print in 300dpi. There's no reason to change pixel-count only because you print at a different resolution. Any print-service I know ignore the dpi-numbers saved in files they get, they all keep an eye on pixel-count. Because that's the number that matters regarding quality since printing machines have a fixed dpi resolution. That's because you will order a fixed papersize anyway. | | | | | | Last edited: by StaNDarD |

6000x4000 is your screen resolution I'd like that screen. | | | First registered: February 15, 2002 |

| Posted: | | | | Printing services may indeed ignore it, since most of their prints are 15cm x 10cm photos. But using higher dpi will give you sharper images. Certainly when using bigger photo formats.
Here is an extract of http://www.iuniverse.com/FAQs/Image-Guide.aspx
Image Resolution When referring to digital images, the term resolution is used to quantify the number of pixels or dots that make up an image. As the number of pixels in an image increases, so do the resolution and clarity of the image. The two standard measures for resolution are dots per inch (dpi) and pixels per inch (ppi). The terms are interchangeable, as both are a measure of the number of pixels within the image. In printing and publishing, the standard threshold for image clarity is 300 dpi. Images with a resolution of less than 300 dpi can appear distorted and pixilated when printed. As with image size, image resolution can always be decreased, but image resolution cannot be artificially increased. | | | View my collection at http://www.chriskepolis.be/home/dvd.htm

Certainly when using bigger photo formats. I see where you're coming from, and if you would like to print a professional book or magazine, you'd be perfectly right. Those printing companies really use dpi-values. But for a simple printing service, that prints your posters you have a fixed size with a fixed ppi. So all that matters is pixel-count. Having the same pixel-count on a fixed papersize, each pixel will take the same size on the paper regardless of the dpi-value of the file. Let's take a DIN-A 1 poster which will be printed in 300dpi: 23.4 inch * 300 ppi = 7020 points A picture with 6000px in 72dpi has to be blown up by factor 1.17 A picture with 4000px in 600dpi has to be blown up by factor 1.755 The first picture will be much sharper though it has only 72dpi just because its pixel-count is nearly perfect. Printing both pictures will show they are nearly the same in sharpness, just because a colored pixel is not printed in one colored point but in multiple colored points - just because it will be a four-colored print and a single point can have only one out of 5 colors (white, cyan, magenta, yellow, black) and not out of 16.4 millions which an image-pixel might have. | | | |
