Resolution to print (10x15cm) (4x6in)

[Fred_]

Hello,

I would like to send pictures to a web site to get (10x15cm) (4x6in) prints.

What I would like to know is what is the resolution to use to get good results?

In lightroom I can set the Heigth to 15 cm and Width to 10cm and resolution 350 pixels per cm, will it be ok?

Thank you

Fred

300 ppi should be sufficient.

I don't concern myself with PPI settings when I'm ordering prints. I just upload the photos. The labs that I use will indicate what sizes will print well from my images, and all I have to do is choose which ones I want. Setting the PPI doesn't really change anything in the image anyway. It's just a setting to help you determine how big the image will be at that setting. It doesn't modify the image.

Thank you for the answers

In fact I don't want to send a high resolution file to the web site... so I try to send only what they need to do the jobs!

Thanks

300 ppi = 118.11 pixels per cm
350 pixels per cm = 889 ppi

As was suggested above, 300 ppi should be sufficient. If you use 350 pixels per cm, you are in essence sending a high resolution image.

10 x 15 cm @ 300 dpi (=118.11 pixels per cm) gives you a good print at 1181 pixels by 1772 pixels.

If you use 350 pixels per cm (=889 ppi), your pixel count increases to 3500 pixels by 5250 pixels. Overkill.

Actually, lpi versus dpi is 2 or if you wanna be save 2.2...so that would yield 136 lpi!

lines per inch is important for print... remember lpi times 2 or 2.2 = dpi!

300 dpi is standard for print.

Most want to have 150 lines per inch... that is 300 dpi or to be save, times 2.2 = 330 dpi!

While I agree with what you said, the previous discussion was about the metric system (Europe), where apparently pixels are counted by "how many pixels per centimeter", and NOT "how many pixels per inch". That's why 889 ppi is overkill for a 4" x 6" print.

I agree, 899 is way overkill. And would yield an unnecesarrely large file!

i have been sending my finished edited but not upsized images to kodakgallery.com and jumbogiant.com for quite awhile. Lately I have been using the scott kelby method of resizing and upping the resolution but not resizing when sending the images to jumbogiant.com. Kodakgallery.com makes my 16X20 and 20X30 in matte. while jumbogiant.com makes my glossies and panoramas. i have been printing to 30inch wide(you can get 40X60 regular and 24X80 panoramas) with jumbogiant. you also have several choices of paper with jumbogiant.com. they seem to be using Epson paper. The biggest I have so far ordered are 20x30 inch regular prints, and 12x48 panoramas and 16x36 panos.

i send my jpeg and they do any upsizing needed. you cannot send raw(which require converting and pp) or tiff(file size is too big).i also have been sending them the image in adobeRGB, they either change them or use them as is. the colors from either company come out great. jumbogiant.com only wants 150ppi as the minamum.

you have to read the information of the printing website and see what they want and will accept.

i would not resize or change the color gamut till you KNOW that the printing online outfit will not accept what you are using. if you have to change only change the copy to the specs you need to send them never the original image.

i have been using adobeRGB and not resizing AT ALL to either outfit with no problems. and by not resizing i mean that i have been sending them every size imaginable and the print are all great from either place. sizes range from 6mp digital shots to unresized 4000dpi digital scans of slides which are still the original scan size(1.4inches X .9inches).
i would not create a problem of your own till you have to.

i print 8x10 and smaller, myself.
