booklets if you can have double sided photocopies - and aerosol stencil

1) Booklets.

Like quires for perfect bind or like centerfold saddlestitch.

A double bifolio is four leafs or eight pages. A n-ple bifolio is 2n leafs and 4n pages. 24 pages can be made as either three double bifolios or six bifolios in each other. 64 pages can be either eight double bifolios or sixteen bifolios in each other.

Pages are couples so that extremes of each quire go together.

Recto: 8-1 Verso: 2-7
Recto: 6-3 Verso: 4-5

Recto: 16-9 Verso: 10-15
Recto: 14-11 Verso: 12-13

Recto: 24-17 Verso: 18-23
Recto: 22-19 Verso: 20-21


Recto: 24-1 Verso: 2-23
Recto: 22-3 Verso: 4-21
Recto: 20-5 Verso: 6-19
Recto: 18-7 Verso: 8-17
Recto: 16-9 Verso: 10-15
Recto: 14-11 Verso: 12-13


64 means quires go on up to:

Recto: 56-49 Verso: 50-55

Recto: 54-51 Verso: 52-53

Recto: 64-57 Verso: 58-63
Recto: 62-59 Verso: 60-61


Recto: 64-1 Verso: 2-63
Recto: 62-3 Verso: 4-61
Recto: 60-5 Verso: 6-59
Recto: 58-7 Verso: 8-57
Recto: 56-9 Verso: 10-55

2) Aerosol Stencil.

A sheet you put between aerosol and object to spray a text or image onto it. Here I deal with text.

a) print or write it on a paper
b) stiffen, either by glueing on to carton or by adding simply adhesive tape all around
c) cut out the letter shapes.

Now, this is the tricky part. Getting good or at least adequate shapes for even 36 p printout (in bold print) resuires some ado, but here is how I went about it. Each line of the text is cut into half (do this for first line only, then do following steps, then go back to do this to next line). Every pole in upper or lower half of a letter is simply excavated. Perfect rounds like letters o or upper and lower round of printed g - certain printing styles, not this one, which is like a handwritten g - are excavated. Any round or branch close to pole is excavated - cut out - except for part closest to pole (a is thus a pole to the right, an upper branch nearly attached to it to the left and under it a half round nearly attached to it, d is a half round nearly attached to a pole on the right, in b the half round and the pole change sides). Any turn is not cut out right in the middle: upper case U and this lower case g both have a bridge in the middle of the lowest part. Either upper or lower case V has the second line only close to first, not onto it. Anything not reachable directly from the cut up side - like a dot over i or accent over é or lower curls of the print only lower case g - will be reached through a slit of the scissor, which afterwards is scotched over. When all is cut out on both sides, put them together again (this is where it is real good if you used card board), scotch outer sides so as to keep anything between real straight as it ws before cut, put over weaker scotch in the middle and before repairing around each letter with small pieces of strong scotch, cut the weak scotch through. When all lines are thus repaired, scotch over any spot of unscotched paper without covering any hole. In the following example there were such cuts three times (or actually not quite the first line, which made cutting out letter shapes harder):

want something to make booklets from? and want some keywords to keep on subject?

Here is a tip for binding quires: - Japanese style bookbinding.

Hans-Georg Lundahl said...

This one starts out with making quires - actually "in octavo": 16 pages per quire (so if you make book from printed sheets the pages on them go like all the way from top images of
Bottom row right side up:
DMPA=recto 4-13-16-1, 20-29-32-17 et c
with a verso row of
BONC=verso 2-15-14-3, 18-31-30-19 et c
under an up side down row, which if turned gives:
recto HILE= 8-9-12-5, 24-25-28-21 et c
verso FKJG=6-11-10-7, 22-27-26-23 et c
Just to make sure you grasp it, B is verso of A, not of D, and it is C that is verso of D. Likewise F is verso of E, not of H, and it is G that is verso of H. Moreover D is under an upside down E, not H, it is A that is under upside down H, just as B is under upside down G and C under upside down F.

Obviously, for one thing, a quire of 16 pages does not need to be printed on one big printing sheet folded three times, it could be printed on two or four of them (folded twice or once). Also, a quire does not need to be of sixteen pages, it could be of only eight pages - or, as said in article even 20 - and a quire of eight pages could either be a printed sheet folded twice or two of them folded once.

Hans-Georg Lundahl said...

While uniting the pages for a printing sheet, you start like

P-A 16-1, 32-17 8-1, 16-9
B-O 2-15, 18-31
N-C 14-3, 30-19
D-M 4-13, 20-29 2-7, 10-15
L-E 12-5, 28-21 6-3, 14-11
F-K 6-11, 22-27
J-G 10-7, 26-23
H-I 8-9, 24-25 4-5, 12-13

Then you couple P-A and H-I so that heads meet, and likewise D-M with L-E, if you have sixteen pages per quire also B-O with J-G and N-C with F-K.

For eight pages per quire PA/HI and DM/LE form opposite pages of printing sheet.

For sixteen pages per quire PA/HI is coupled with DM/LE so that DM is to left of PA. Likewise on other side of print sheet BO/JG joins NC/FK so that BO is to left of NC.
