The memorial and District convention invitations have a space for each congregtion to put their local information on them.
The congregations then have to foot the bill, many times it is the service overseer personally, for the printing on them.
Some print labels and the congregation puts them on, others print with their laser printer and wear them out.
At first the paper was so poor that the particles would destroy laster printers and make a dust storm. Commercial printers hated that paper.
The Society should have a variable data printing system since they know the times of the memorial and convention for each congregation and they should print that while they print the initial invitation.
Think if it, 12,000 congregations in the USA multipled by $50 on average cost to print or label each congregation's amounts to $600,000. Do that twice a year for 7 years and that is $8.4 million dollars. A variable data print head system attached to their press and ink would be far less than that. It may slow the presses down.
What a waste of money for the congregations and they get nothing for it.
