@foone A trick that I used back in that time (UV sensitized boards were too expensive for me) is to photocopy on ordinary paper the circuit, then put it on top of a bare copper clad board, use a nail to gently mark the position of each hole through the paper, use a pen to trace manually the tracks by copying the best I could the tracks and finally etch the board and drill the holes. You save the UV transfer project, but it quite error prone and slow.
