CUT AND PASTE

  • Highlight the text you want to Cut and Paste
  • Hold down the Ctrl key on your keyboard
  • Press the letter C or X on your keyboard
  • The text is cut
  • Move cursor to position you want to paste your text
  • Hold down the Ctrl key on your keyboard
  • Press the letter V on your keyboard
  • The text is pasted to the new position

GETTING THE CORRECT RESOLUTION

How to ensure you have the right resolution and size for your image:

Resolution simply refers to the clarity of raster images when we view them. Raster images are images like photographs or graphics particularly with the file extensions jpg and png.  Raster images are displayed in pixels. The more pixels in an image, the crisper and cleaner it looks around the edges and the clearer it becomes. Thus, the larger copy we can print.

So here’s how it works:

The naked eye can see at around 300 dpi, or 300 dots per inch. This is the standard resolution required so that images may appear sharp and concise when viewed by an average pair of eyes. If the images are too low in resolution however, they will look grainy and pixellated when printed, even if they look fine on your computer screen.

Understanding resolution is extremely important when it comes to printing out images, especially in books and publications. The simple rule of thumb is that the image MUST be a minimum of 100% of it’s original size when saved in a print ready layout like a PDF file. That means if you have to enlarge it to make it fit your page area, then you have just lowered the resolution and your image will possibly appear looking sub-standard.

By ensuring the correct resolution, your printed images will be of the highest quality when viewed on your book pages. If you understand how resolution relates to finished size (i.e. pixels to millimetres) then you will be able to calculate your requirements any time you need.

Resolution TOO LOW

If the resolution of your picture is too low, or below 300 dpi it risks the pixellated effect when you view it and may not be suitable to use for your book. Small raster images cannot be resized larger, without this occurring.

Resolution TOO HIGH

You can reduce the size of a larger image to fit a smaller area without losing clarity. However this means larger, clunkier files as a result that take up more memory space. In other words, it’s overkill and simply unneccessary.

To work out the resolution for an image to appear on a book page for example, you need the finished book page size and also the finished size you want the image to be, in millimetres (mm).

See below for the ratio of pixels to printable millimetres. Using the mathematical formula you will be able to work out the size image you need and the minimum amount of pixels for the height and length.

The references for each are as follows:

  • 1 mm3.779527559 pixels
  • 1 pixel0.264583333 mm

So, to clarify, for every 1 millimetre of printed image you need exactly 3.779 pixels to maintain average viewing resolution of 300dpi.

To calculate the actual resolution, multiply height and length measurements by the pixel ratio of 3.779 and the total sum is the image dimensions in pixels, or the resolution that would normally required for that size photo.

Say your image takes up the whole A5 page, like a background and you are going to lay the text on top. Your finished image needs to be resized exactly to the book page size (148.5 mm x 210 mm) plus you need to allow bleed margin of 5mm. This way, when trimmed, the image is exactly to the page edge. So your required size for finished image is 158.5mm x 220mm.

To calculate the actual resolution, multiply both measurements by the pixel ratio to millimetres as shown above

For example:

  • 158.5 mm x 3.7795 = 599.05 total pixels
  • 220 mm x 3.7795 = 831.49 total pixels

Therefore the resolution required for a 158.5 mm x 220 mm image is:

  • 599.05 pixels x 831.49 pixels

Follow this formula to calculate your sizes. Then all your images will be spot on and rest assured, there will be no grainy or pixellated junk on display in your publication.

Is your Image already the correct resolution?

To work out if an image you already have is the correct resolution to use for your book page, divide the image dimensions in pixels, by 3.779. The result is the size required for your image when printed at 300dpi. Check this is the not too small for the finished size you want for your page. If it is, you need to acquire a larger initial image or risk a grainy pixellated outcome.

Resolution TOO HIGH?

Images can be slightly oversized or a marginally higher resolution than required. However, if images are drastically oversized, for example 1200dpi or larger they gain no extra clarity when reduced but will result in larger clunkier files which use more memory.


LINKED IMAGES vs EMBEDDED IMAGES

If you are incorporating images in your layouts, knowing the difference between an embedded image and a linked image can be useful. When you import an image, once selected, the import module will ask you if you want to link the image or embed it. You must choose one before proceeding with the importation of your image.

A linked image is an image that is linked to an external file or folder, like a shortcut on your computer.

An embedded image is an image that is re-stored within the new file you’re creating.

Linked Images:
  • Are not a part of the new file so the file size is smaller
  • Can be easily updated
  • Updated images replace the existing ones automatically
  • Can be lost as you cannot move to another folder without re-linking
  • Must be in same file folder as corresponding artwork if emailing
Embedded Images:
  • Become a part of the new file
  • Increase the size of the file
  • Are not affected by ANY changes to the original file.
  • Don’t get lost as they are embedded in the new file
  • Negate sending seperate images in same file folder when emailing

RESIZING AN IMAGE

If you have Windows you will automatically have installed on your computer a free version of a program called Paint. It may be hidden in the Accessories area but it’s there. Find it, open it and proceed as follows to resize your image. The image must be one of the following formats as these are the only types Paint can open:

  • JPG
  • PNG
  • BMP
  • TIFF

File > Open

Go to folder or area on computer where image is stored. Click on image then Open, or double click on the image and it may open automatically.
