There have been a few posts on engraving glasses and the distortion you get. There was recently a question on tapered glasses. Several people answered with good but only partial answers. As others mentioned as the diameter gets smaller so does the engraving area, hence the taper. Without getting technical, I wrote an Excel sheet to calculate the distortion needed to compensate for straight tapered glasses. I have tried to make it user friendly. When you open it there is a picture of a glass on the "input" side. Fill in the requested dimensions and the distortion dimensions will show on the "output" side. Just go into Corel and use the Envelope function to distort your graphic.
I did a sample on a plastic glass (this all I could find at the time). Hopefully the picutres below will show the difference. And the Excell sheet is also attached for you use. I would be interested in how this works out for others also.
I hope this helps.
