|Abstract or Summary
- The objective of this thesis is to examine and compare hot
metal and cold type production of display advertising for newspapers.
The classical hot metal system uses a lead alloy as its basic building
material while modern cold type production uses photographic
means. Some advantages of using cold type are the improved quality
of the final product, increased versatility in ad composition,
possibilities for major labor savings, the lower skills required
for the compositor and less production space required for the
machinery. Some disadvantages of cold type production are the
major investment required for new equipment, higher materials
costs, difficulty in producing proofs, labor relations and retraining
difficulties, and the durability of the press plates.
The data for the hot metal method consisted of a sample of
195 ads. The eight major operations studied were Markup Time,
Type Slips Time, Stereotype Time, Typesetting Time, Composing
Time, Proof Pulling Time, and Correction Time. Thirty-seven factors,
such as the size of the ad and the number of lines of type, were
hypothesized to effect the operation times. These operation times
and factors were analyzed by multiple linear regression analysis
to formulate a mathematical model of the hot metal system. For
this cold type system, circumstances prevented making a complete
model but data for a sample of 15 ads was collected.
The data for the sample of cold type ads was used in the hot
metal regression model to determine comparable times for production
of the ads by both systems. Experimental results showed that
it would take three times as long to compose the ads by hot metal.
When combined labor and materials costs are considered, hot metal
costs 1.6 to 2.8 times as much as cold type depending on the wage
rates considered and the relative productive efficiency of both plants.
Administrative and most overhead costs were considered to remain
constant no matter what production system was used. The depreciation
rate for the cold type operations is 3.06 times that of the hot
metal system studied.
Recommendations for further study include:
1. Reevaluate hot metal regression model using transformations
in order to reduce non-linearities.
2. Reformulate the cold type system so that equivalent
production work can be measured to produce a cold type regression model.
3. Extend the study of cold type and hot metal into news
and classified production.
4, Use the complex regression models to determine major
variables so that simplified models could easily be prepared
by any interested newspaper.
5, Determine realistic cost comparisons including the
effects of unequal depreciation rates, taxes, and interest.
6. Produce a companion study of the social effects of a
transition from hot metal to cold type in order to be
able to project actual benefits derived from the transition.
