Preparation of a handful of pages for print

I have these pages in pdf and Affinity Photo to convert text to k only and ensure colour tint is consistent, and maps are cmyk

7AP: CMYK black text

86AP: CMYK black text
Route & numbers now a variety of tint values

91AP: RGB map
CMYK black text/page number

106AP: numbers 27 92 0 0
CMYK black text

107AP: mix of rastered and vectored text
Mix of CMYK black text & K only black text

134: RGB map
Otherwise spot on!

134AP: as above but with CMYK black text

135AP: CMYK black text
RGB map
