This tool can be used to create PDF writing sheets for Korean. You enter the Korean text that you want and then you can get custom PDF Korean worksheets to practise your Korean. The standard (basic) settings show how things can be laid out. The basic settings the characters/letters are set to fade automatically across from strong to almost invisible across the page (later in the advanced settings you'll see this under gradual face selected). There is also Korean romanisation above the characters in the copybook worksheets.
For the advanced Korean worksheet tools, you can choose the size of the paper, whether it is portrait or landscape, the size of the rows, if you add titles to the page so for example Korean Lesson Sheet Number 1 etc. There is also the option to change the Korean worksheet font, change the romanisation location, change the size of the hangul and Hanja.
Character display means whether you just see one hangul individually or a word together. Ie one line of just 안 followed by 녕 or one line of 안녕 followed by 안녕. You can choose how dark the characters are so that you can work out the best copy book for you. There are lots of different Korean grid styles which you can use on the advanced systems depending on which one you are most used to. You can also change the row or column spacing.
