Who's ready for more type knowledge? Doesn't matter, you're getting it anyway.
Interesting fact #1: When making a metal font, there were two punches in it's creation. The first punch took care of the outer shape followed by a second, or counter, punch. This counter punch handled the interior portions of your letterforms. This is why we refer to the interior portions of our letters as "counters".
Interesting fact #2: Our paper is classically rectangle due to the shape of skinned sheep. This is because the widest portion of a skinned sheep is it's back. I suppose people felt unnerved by the hanging limb skin, lopped them off and ended up with a rectangle.
Interesting fact #3: When setting your type in a letterpress studio you use what is called a "composing stick." You use lead for your line spacing, hence the reason it's referred to as "leading." When referring to your set type you'll use a fraction. This fraction uses the font point size over the top of that same size plus the thickness of your leading. For example, you use a 12 point typeface with 2 point leading, you would refer to that group as 12/14. With your 12/14 group you must remember to set your letterforms with the notch up. Remember, with a small font, it may be wise to utilize an em space at the beginning. This makes it easier to transport from your composing stick to the press. Another key tidbit is to make sure you use your largest filler material at the end of your line.
Stay tuned next week for the inclusion of my press printing work. I'm still just a baby here and haven't yet begun to crawl. I don't advise having a crawling baby in the letterpress studio by the way, you might as well have he/she lick the walls of your peeling walls that were painted in the 70s.
