00:01:00.000 --> 00:01:00.000


4
00:01:14.860 --> 00:01:17.640
For thousands of years

5
00:01:17.640 --> 00:01:24.420
Artists have drawn in precise line on cave walls papyrus parchment and paper

6
00:01:24.980 --> 00:01:32.460
The line is incisive it delineates and purifies the exact detail the artist pictures in his mind

7
00:01:35.140 --> 00:01:42.300
The line broad or narrow long and sweeping or drawn in short strokes stipple and dots

8
00:01:42.860 --> 00:01:46.140
Makes shading of infinite richness and depth

00:01:54.420 --> 00:01:54.420

Overlays line online and creates luminous shadows and

11
00:02:16.560 --> 00:02:19.580
Soon the single line has become form

00:02:20.340 --> 00:02:22.480
dimension mass

13
00:02:23.200 --> 00:02:29.100
The pen scribes millions of lines in the creation of art and the surface of the paper

14
00:02:29.700 --> 00:02:31.880
Becomes a partner in the act

15
00:02:37.460 --> 00:02:44.540
Today a most important function of the line in contemporary graphics is to maintain accuracy

16
00:02:46.480 --> 00:02:47.200
exactness

17
00:02:47.200 --> 00:02:55.900
Reproducing a design concept in print requires absolute detail and this requires a precise drawing a key line

18
00:02:55.900 --> 00:03:02.800
To establish borders of half tones solid colors screen tints as well as line illustration

19
00:03:02.800 --> 00:03:05.920
drawings lettering graphs and charts

20
00:03:06.640 --> 00:03:09.440
The key line is the basic plan

21
00:03:09.440 --> 00:03:14.080
It's the guide for the new sophisticated processes of printed reproduction

22
00:03:14.720 --> 00:03:21.720
There is no mass printing without engravings and there is no engraving without original art

23
00:03:23.460 --> 00:03:26.180
The key line begins with a line

24
00:03:26.180 --> 00:03:29.860
To draw the final line in proper position and thickness

25
00:03:29.860 --> 00:03:32.080
Requires a special skill

26
00:03:32.080 --> 00:03:39.660
But the material the paper on which the line is drawn is a critical factor in the preparation of working drawings

27
00:03:39.660 --> 00:03:44.180
The paper must respond to each need of this precise skill

28
00:03:44.180 --> 00:03:51.700
It must respond to the pen to the pencil to the brush with a surface that supports and enhances the line

29
00:03:53.020 --> 00:04:01.860
line coat illustration board a product of Crescent cardboard company is the final answer to a long research and development program

30
00:04:01.860 --> 00:04:07.360
to perfect a surface that provides the finest ink line possible a

31
00:04:07.360 --> 00:04:14.260
Process created a coated sheet that renders super fine lines without clogging pens

32
00:04:15.200 --> 00:04:18.680
Until recently hot press board was the standard

33
00:04:19.760 --> 00:04:28.280
Magnified hundreds of times through the electron microscope these comparative photos show the present surface of hot press board and

34
00:04:28.820 --> 00:04:31.560
the finer grain top surface of line coat

35
00:04:32.280 --> 00:04:34.120
These are the results

36
00:04:34.120 --> 00:04:37.040
The edge of the ink line on hot press is

37
00:04:38.220 --> 00:04:44.260
Irregular on line coat the line is pure and the edge is accurate and sharp

38
00:04:44.920 --> 00:04:52.160
When lines are drawn over each other the cross hatching does not fuzz since the surface of line coat does not fray

39
00:04:54.500 --> 00:04:57.040
Corrections don't destroy the line coat surface

40
00:04:57.860 --> 00:05:02.520
Slight errors are scratched off and the ink can be removed with an abrasive eraser

41
00:05:03.040 --> 00:05:07.520
After which another line can be drawn clearly over the erased surface

42
00:05:09.020 --> 00:05:13.760
Slight burnishing caused by metal instruments are removed easily with a plastic eraser

43
00:05:14.600 --> 00:05:21.600
wiping with a dry cleaning pad removes oil and grease prints without removing pencil lines and

44
00:05:21.600 --> 00:05:25.080
Rubber cement is removed easily after paste-up copy is applied

45
00:05:32.620 --> 00:05:38.620
Transfer letters apply with ease on line coat yet tape picks up without marring the surface

46
00:05:38.620 --> 00:05:39.580
Transfer letters apply with ease on line coat yet tape picks up without marring the surface

47
00:05:39.580 --> 00:05:46.160
Pencil lines are blacker on line coat ink lines never gray out when pencil is removed with a plastic eraser

48
00:05:48.000 --> 00:05:53.160
Line coat is the contemporary answer for sharp ink line drawings

49
00:05:54.360 --> 00:05:59.580
The reproduction of graphic art begins on a simple board

50
00:05:59.580 --> 00:06:07.220
Packaging periodicals newspapers posters corporate graphics all of the visual graphics media

51
00:06:07.220 --> 00:06:11.120
depend on the accuracy of the drawing needed to produce them

52
00:06:11.120 --> 00:06:17.720
This accuracy is critical and dependent on the edge of a line
