The reality is: If it is an older top (pre 1990's) they won't come out. The process prior to that time was stamped and heat pressed. The ink had a wax in it so it is almost set forever. In time with repeated washings they will lighten up. After the 90's a water base ink was used. HOWEVER, to my knowledge none of the overall printed designs were or have been printed in the wash out ink. It sounds like it was a made from a kit contained the printed background with fabrics to do the applique. Also another way to judge the age is if the lines were small dotted lines. I do hate to give you this information. I suggest you contact the place where you purchased it and if they continue to sell them then to warn abour the lines. You don't say you got it at a quilt shop or other place.
