Use a graphics programme that can export EPS-file for electronic submission. At first submission, embed your graphs in the word processor file, but save the EPS-files for final submission after acceptance.
Avoid frames around diagrams and diagrams with perspective drawing. Symbols should be consistent throughout a series of figures. Different types of connecting lines can also be used. Make diagrams in black-and-white, grey or colors but avoid complex patterns.
Axes should be equal in length to make the diagrams square. Each axis should be horizontally labeled with a description of the variable it represents. Use capitals only for the first letter in the first word. Use SI units. Make liberal use of scale markings, directed outwards, but identify only a few with numbers. Axes should not extend beyond the last numeral and never be terminated by arrows. If an axis is not continuous, this must be indicated by a clearly demarcated interruption. The axes print well when they are 9 cm long and 1 p wide and the scale markings 0.5 p wide. Labels should be sans serif letters (Arial or Helvetica) in 18 p. Numbers at the scale markings should then be 14 p.
If drawings or graphs are originally on paper only, scan them using bitmap (1 bit TIFF) and if appropriate aim at a 70 x 70 mm scan with at least 800
dpi
Dots per inch (DPI) is a measure of printing resolution, in particular the number of individual dots of ink a printer or toner can produce within a linear one-inch (2.54 cm) space.
resolution. File size will be >600
KiB
A kibibyte is a unit of data storage that equals 2 to the 10th power, or 1,024 bytes
but can be LZ compressed without quality loss. For line graphs don not use gray-scale.
