Requirements

Starting a new year

Clone the template and calculate the moonday and event data in CSV for the year.

git clone https://github.com/profound-labs/fs-calendar-template.git ./2020_main
cd 2020_main
rm .git -rf
make calculate-data YEAR=2020

Edit year and altYear class options in wall.tex and desk.tex:

  year=2020,
  altyear=2563,

Test compile:

make wall
make desk

First commit:

git init
git annex init "2020 calendar"

git annex add images
git commit -m images

git add -A
git commit -m first

Crop the photos from the originals and replace the placeholders:

git annex unlock images/jpg/* images/pdf/*
rm images/jpg/* images/pdf/*

# Copy in the new .jpg files, then covert:
make jpg-to-pdf

git annex add images/jpg images/pdf
git add -u images/jpg images/pdf
git commit -m "cropped images"

Improve photos:

  • Auto White Balance
  • Desaturate manually Lightn. / Lumin. / Avg.

PDF Colors

Don't use [cmyk] option on xcolor package. Declare text colors either in gray or cmyk (for color).

Images should be Grayscale colorspace.

PDF should embed Fogra29 profile.

Kenny uses Photoshop to convert the calendar to Black + Pantone 1245 C.

Converting photos to grayscalse

GIMP

Use the Channel Mixer:

https://www.gimp.org/tutorials/Color2BW/#channelmixer

Then adjust Brightness and Contrast.

Cropping and resizing photos for landscape layout

Three-side bleed is best if the images allow it.

Lock the aspect ratio of the selection tool in the image editor, then you can forget the numbers, and resize the selection area to the crop that is best.

Calendar sizes:

Trimmed paper size: 6.75in x 10.5in = 171.45mm x 266.7mm

Photo width: 171.45mm + 2*3mm bleed = 177.45mm

Photo height: 150mm + 3mm, covering wire and top bleed

Photo height: 140mm, when two side bleed

Calendar height, including events: 85mm + 3mm bleed = 88mm

Quote, four lines, 14/18pt = 72pt + 6mm spacing = 25.4mm + 6mm = 31.4mm

Vertical sizes:

p c
top bleed + 3mm
wire punch + 10mm
photo + 130mm
quote
cal headings +
day headings + 5mm
calendar grid +
events +
bottom margin + 10mm

Most years have one or two months with three uposathas and the notes text allow for three lines.

Notes for three uposathas: x

Ratios

Full-page ratio: 1.5555 = 2400px x 3733px

Three-side bleed resolution: 1.1598 = 2087px x 1800px

Three-side bleed resolution: 1.3342 = 2400px x 1800px

(? desk) Two-side bleed resolution: 1.2675 = 2028px x 1600px

Two-side bleed wall resolution: 1.47875 = 2366px x 1600px

(Image is 177.450mm x 120.000mm)

Desk resolution: 1.3369 = 1605px x 1200px

(Image is 123mm x 92mm)

123/92 = 1.33695652174

Photo width: 171.45mm + 2*3mm bleed = 177.45mm

Photo height: 150mm + 3mm = 153mm

Photo height, less: 130mm + 3mm = 133mm

Three-side bleed ratio: 177.45 / 153 = 1.1598

Three-side bleed ratio: 177.45 / 133 = 1.3342

Two-side bleed ratio: 177.45 / 140 = 1.2675

177.45 mm = 6.9862 in 153 mm = 6.0236 in 140 mm = 5.5118 in 133 mm = 5.2362 in

6.9862 * 300 = 2095.86

6.0236 * 300 = 1807.08

5.5118 * 300 = 1653.54

5.2362 * 300 = 1570.86

Three-side bleed

For a three-side bleed, the images have to fill a space 177.45mm wide and 229.7mm tall, this already includes 3mm bleed left and right, and 3mm on top.

The pixel size can be different from photo to photo, but the ratio of the sizes should be the same. When you divide the height with the width, the ratio should be about 1.2944.

This means you can crop smaller, but the aspect ratio of the crop should be the same.

In the ideal case where they all have sufficient size to crop from, aiming at 300dpi for the cropped images, it translates to (height x width): 2712 x 2095 pixels.

Checking the ratio: 2712 / 2095 = 1.2945.

Two-side bleed

For a two-side bleed, it is good to leave about 10mm empty space at the top, and there is no top bleed, so that is an area 177.45mm wide and 216.7mm tall.

The ratio of that is 1.2211. At 300dpi, in pixels (height x width): 2559 x 2095.

Portrait, Two Side: Two-side bleed

Photo is full height, on the left or right side.

The photo width is 2/3 of paper width.

Photo has bleed cut on top and bottom, plus one of left or right.

(NOTE this is for bleed on left or right side only)

(FIXME: 220? not 266?) Width: 220 * (2/3) = 146.66 + 3 = 149.66

Height: 171 + 6 = 177

Ratio: 177 / 150 = 1.18

In pixels for 300dpi: 2090 x 1771 px

177mm = 6.9685 inch 6.9685 * 300 = 2090.55

150mm = 5.9055 inch 5.9055 * 300 = 1771.65

Portrait, One Side, Large Calendar, Two-side bleed

The photo width is 2/3 of paper width.

The photo height extends 1cm below the half-height line.

Width: 171 * (2/3) + 3 = 117.0

Height: (266/2) + 10 + 3 = 146

Ratio: 146 / 117 = 1.24

117mm = 4.6062 inch 4.6062 * 300 = 1381.86

146mm = 5.7480 inch 5.7480 * 300 = 1724.4

In pixels for 300dpi: 1400 x 1736 px

500*1.24 620.

Editing

  • open JPG
  • Add Alpha Channel
  • check if Color > Levels will improve contrast
  • Desaturate, use the one with better contrast
  • look at the desaturation with zoomed out image
  • test is Color > Brightness and Contrast can improve the image
  • Select All, then Image > Guides > Guides from Selection
  • create selection with fixed size ratio
  • Select > Save to Channel
  • save as .xcf

Export:

  • crop to selection
  • scale image
  • change color mode to Grayscale
  • Export as JPG
  • export with max 95% compression, no need for 98% and such
