I set myself the challenge to create 30 designs for an adult coloring book, and publish it in 30 days using CreateSpace.com (CS).
How am I doing?
It’s taking much longer than I expected 🙁
The designs were going to be done in one go, so I decided to check how CS want the designs. I know some people who have had messages saying images need to be around 300 dpi so I wanted to check.
Found it in the Interior Reviewer Guide under Image Quality, Low Resolution Images:
“All digital images have a “resolution,” which is a measurement of the amount of detail an image has. The higher the resolution, the more detailed and clear the (image) will be.. For an image to be high-resolution, it is generally considered to have 300 or more dots per inch (DPI) when the image’s dimensions are at the size at which you want it displayed…”
So glad I found that!
Finding image resolution in Windows Explorer.
Right-click on image. Dropdown menu appears.
Go to the bottom to Properties. Left-click to open.
Four tabs – General, Security, Details, Previous Versions.
Open Details. Go to Image.
For the purposes of this, the fields you want are Dimensions and resolution.
The mandala I did has Dimensions 800 x 800 (that’s pixels) and resolution 72 dpi.
CS want Dimensions 2400 x 2400 pixels (px) and resolution 300 dpi.
How to Make Your Adult Coloring Designs Ready to Publish.
I use two free programs, Inkscape and Gimp.
- Open Inkscape and Gimp
- Choose your design
- In Inkscape – File, Open, <yourfilename>. Click Open
- jpeg bitmap image report box will open. Click OK.
- File, Save As
- A window will open with <yourfilename> and Save as type: Inkscape SVG (*.svg). Click Save.
- Inkscape window will open with your design in and <yourfilename.svg> at the top
- Check the folder <yourfilename> came from. There’ll be a .svg file where the Inkscape logo is and it’ll have <yourfilename> below.
- In Gimp – File, Open, find <yourfilename.svg> in the dropdown list and click on it. <Yourfilename.svg> will display in the right sidebar.
- Click Open.
- A new window will open, Render Scalable Vector Graphics.
- The top two boxes are Width and Height. Highlight and overtype the width and height you want. You can change the unit of measurement.
- Ignore the next two boxes.
- The next box is Resolution. Highlight the number and overtype the dpi you want. If you’re printing or publishing, you need at least 300.
- Click OK.
- File, Export.
- An Export Image window will open. <yourfilename.svg> will be in the top field. Change .svg to .jpg.
- got to bottom right corner above Save. There’s a box, “All export images”. Click the dropdown menu and click JPEG.
- Click Export.
- A box will pop up telling you “A file named “yourfilename.jpg” already exists. Do you want to replace it?” Click Replace.
- A box called Export Image as JPEG will appear with Quality and a slide beside it with a number the other side. Move the slide until the number is 100 then click Export. <yourfilename.jpg> will go back to the folder you got it from.
- Find <yourfilename.jpg> in the folder it exported to. Check Properties, Details to make sure the dimensions and dpi are correct.
That’s all there is to making your adult coloring designs ready to publish.
