    I need to make an image 2.375 H and 3W and it needs to be 300dpi. I can figure out the H&W, but how do I set the resolution at 300dpi? I have my setting at archival.

    Hi Tanya,

    Thanks for contacting us! Ribbet doesn’t actually have a DPI setting, but the dimensions will determine the “dots per inch” when printing. So for 2.375×3″ @ 300DPI the dimensions would need to be:

    2.375×300 x 3×300
    = 713 x 900

    Let us know if we can be of any further assistance!

    I have a jpeg image that was provided to me for a book cover. The book will be 5.5 x 8.5 inches and the image will be smaller placed in the middle of the page. The scanned image is 8.5 x 11 inches but is only 150 dpi. The publisher would like the image to be 300 dpi. How can I reduce the size of the image and thus increase the dpi? When I tried to reduce the size, it just kept the dpi at 150.
    Thanks.

    Hi Laurie,

    Thanks for contacting us!

    If you create a Blank Canvas at 1650×2550 this will be the book cover at 300DPI. You can then drag on your image from the Photo Basket (at the bottom of the editor) and resize it smaller. As long as you don’t resize it larger than its original size, you will maintain a high quality, and the resulting image will be 300DPI for the book cover (including the blank space around your image).

    Let us know if you have any further questions.

    I tried creating a blank canvas at 1650×2550 and placed image in it and resized to 1200×1855 and when I saved it on my computer, the dpi went down to 96 dpi. I tried saving it with the different compression options for better quality and it still remained at 96 dpi. What am I doing wrong? Thanks.

    Hi Laurie,

    Images themselves don’t have a DPI. There is a DPI stored in the image’s EXIF data, however this is meaningless (you can learn more here).

    DPI refers to how many dots there are per inch when printed, and the smaller you print an image, the higher the DPI will be. So, a 1650×2550 image will have a DPI of 300 when printed at 5.5×8.5 inches. When printed at 2.75×4.25 inches, the same image will have a DPI of 600.

    I hope this is clear. Please let us know if you have any further questions!

    I created a logo using Ribbet and it was saved at its standard quality that you have at a default setting (“8” is the number I believe it’s at, out of 10). The image itself is 533×439. My client who is using the logo says he needs the DPI to be at 700, as it will be printed at 4ft by 4ft. When I’ve sold my designs to people in the past, it’s simply the design, and not a printed image. When I’ve done this, none of them seemed to have a problem with printing…Upon researching this, my idea is that it’s based on the printer itself more than the program or image…Or am I wrong?

    I read in your previous replies that it’s not in the image itself, but in it’s EXIF data – I clicked on the link you provided and was more confused than Trump reading the 1st Amendment. My question is, is there a particular size for a blank canvas that I need to use in order to get an image with a 700 PPI/DPI resolution, so that it can be printed at a larger scale without distorting the picture? I’m a bit lost on all this as this has never been a problem in the past.

    Thank you for any help you provide.

    Hi Nate,

    In answer to your questions:

    – The image size and quality itself is just as important as the printer – the larger the size you want to print at, the greater the dimensions your image needs to have. The only exception to this is with “vector” images, which Ribbet doesn’t support.

    – The DPI issue can be confusing, but to simplify, here’s the equation:

    Image dimensions = (width in inches x DPI) x (height in inches x DPI)

    So, for example if you want to print at 4ftx4ft at 700DPI, your image would need to be:

    (48×700) x (48×700)
    = 33600 x 33600

    This is an extraordinarily large image though, and Ribbet is only capable of dimensions up to 16 megapixels (4000 x 4000) which is approximately 13.3″ x 13.3″ at 300DPI.

    I would ask your printer if a 4000×4000 pixel image will be large enough. If it is you can create your Blank Canvas at this dimension. If not, you unfortunately won’t be able to use Ribbet for this project.

    Let us know if you have any other questions.

    Thank you for your response, that’s what I figured. I’m trying to do this on Pixlr from scratch but having a difficult time understanding all of its properties.

    Hi Gloria,

    Thanks for contacting us. The dimensions will be 1200×1800. You can also select 4×6 or 6×4 from the constraints drop-down on most tools (Crop, Blank Canvas, when creating a Collage in the Snap dropdown etc).

    I really like Ribbet for making flyers for my camps and classes BUT when I have them printed out, they are so grainy that I cant use them. what should the settings be for a color 8×11 flyer? does that make sense? thank you very much.

    Hi Sue,

    Thanks for contacting us. To ensure that your 8×11″ flyer is printed without any graininess, you need to make sure that your edit has a resolution of 2400×3300 or higher. This will allow printing at 300DPI which is optimal. If you need to, you can use a resolution as low as 1200×1650 (this will print at 150DPI), but any lower and the graininess you’ve described will begin to show.

    Basically the higher the resolution you use the better and will result in the best quality printout. This resolution can be entered when creating your Blank Canvas. If you’re starting with a Grid Collage instead, make sure you have Quality set to High on the top toolbar. If you’re editing a photo, make sure the photo is a full resolution image.

    You can also change your Image Quality setting to Archival (click Hi Username! on the top right toolbar to edit this setting) and this will allow the maximum supported resolution to be used with Ribbet.

    I have a friend that I edited pictures for. When she is trying to print them 5×7, 8×10, and 11×14 they are saying low resolution and they look VERY pixelated. The images appear clear on my PC but I’m wondering if there is something that I can do to make them look better when printed at the above mentioned sizes? I appreciate any input I can get. Thank you.

    Hi Sarah,

    In order to maximise the resolution you need to make sure that you start with as large an image as possible. For the largest size you mentioned – 11×14, to print at high quality (300DPI) you’ll need to start with an image that’s at least 3300×4200. To do this, you will need to first change your Image Quality setting to Archival (you can find your settings by clicking Hi Username! on the top right toolbar within the editor).

    What proportions do I need for a 8.75″ x 11.25″ I found the 1623 x 2100 but how do I get it there?
    Thanks,

    Hi Stacey!

    At 300DPI, 8.75×11.25 is 2625×3375. For Blank Canvas you can enter these dimensions directly.

    For a Grid Collage, as this is larger than a standard size collage, you need to first change your Image Quality setting to Archival (you can find your settings by clicking Hi Username! on the top right toolbar within the editor), and then change the quality on your collage to High (on the top toolbar). You can then drag the edges of the collage until you reach this size by watching the dimensions in the Zoom box down the bottom right of the screen (I’d suggest designing your collage first and then dragging the edges as otherwise the dimensions may change as you change your collage). You may not be able to get the dimensions exact to the pixel, but a few pixels off won’t matter.

    Hi Stacey,

    Sorry I’m not certain what happened to your previous post. The answer is, for a 7 x 10.5 Blank Canvas use 2100 x 3150.

    I need help with sizing. I wish they used inches or had an option for that. I need to know what a 7.75″x10.25″ would be AND 7.75″x5″ would be.

    Thank you for your help!

    Hi Stacey!

    We will add support for entering inches in a future update. For now, here are the dimensions you requested:

    7.75″ x 10.25″ = 2325 x 3075
    7.75″ x 5″ = 2325 x 1500

    By the way, the way to calculate this is simply multiple the inches by 300. So 7.75 x 300 = 2325. This is the calculation for 300DPI which is the standard print quality for most printers.

    What width and height do I need for an 8×10? Thanks.

    Hi Jessie!

    You can achieve this by selecting Custom Ratio… from the Preset dropdown and then entering your dimensions of 8 and 10. This is a relatively new feature and lets you specify any custom size without requesting the required dimensions here.
