be of equal length: whatever difference 

 there may be in the width of the type 

 is compensated by spacing blocks be- 

 tween the words. This is known as 

 "justification." Having accomplished 

 the foregoing, the printer is now ready 

 to clamp the type matter in a suitable 

 frame and place it on the press. 



Setting up the type and printing does 

 not complete a printing job. There still 

 remains another task for the printer to 

 do. He must take the type out of the 

 clamping device and place every indi- 

 vidual type back in its proper place, so 

 that it will be available for the next job. 

 Obviously, it would be foolhardy to use 

 the type but once and then discard it. 



The typesetting machine was a neces- 

 sity. It had to come. While typesetting 

 by hand was practicable for small jobs, 

 it was certainly unsatisfactory for large 

 printing jobs such as newspapers and 

 magazines. Not only was it exceedingly 

 costly, but it lacked the speed which 



daily newspapers made imperative. De- 

 spite the many mechanical problems pre- 

 sented in evolving the typesetting ma- 

 chines, the ever - increasing demand 

 caused it one could say with impunity, 

 forced it to be invented and subsequent- 

 ly perfected.

machine is a two-fold one: it casts its 

 own type and sets it up in proper order. 

 And what is more, after the type has 

 been used it can be thrown back into 

 the melting pot of the machine and the 

 metal used over again for the next job. 

 Not only is it unnecessary to take up 

 time in distributing the type, but fresh, 

 clean, sharp type faces are available for 

 each printing job when using the type- 

 setting machine. 



Let us examine one of the typesetting 

 machines, the linotype, and study how it 

 performs the various functions which 

 are so human-like: In general appear-
